Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
double *sum_n_avg(double n1, double n2, double n3);
int main () {
double n1, n2, n3;
cout<<"Enter 3 inputs: ";
cin>>n1>>n2>>n3;
double *p;
p = sum_n_avg(n1,n2,n3);
cout<<"Sum: "<<*(p + 0) << endl;
cout<<"Average: "<<*(p + 1) << endl;
return 0;
}
double *sum_n_avg(double n1, double n2, double n3) {
static double arr[2];
arr[0] = n1 + n2 + n3;
arr[1] = arr[0]/3;
return arr;
}
Explanation:
This defines the function prototype
double *sum_n_avg(double n1, double n2, double n3);
The main begins here
int main () {
This declares variables for input
double n1, n2, n3;
This prompts the user for 3 inputs
cout<<"Enter 3 inputs: ";
This gets user inputs
cin>>n1>>n2>>n3;
This declares a pointer to get the returned values from the function
double *p;
This passes n1, n2 and n3 to the function and gets the sum and average, in return.
p = sum_n_avg(n1,n2,n3);
Print sum and average
cout<<"Sum: "<<*(p + 0) << endl;
cout<<"Average: "<<*(p + 1) << endl;
return 0;
}
The function begins here
double *sum_n_avg(double n1, double n2, double n3) {
Declare a static array
static double arr[2];
Calculate sum
arr[0] = n1 + n2 + n3;
Calculate average
arr[1] = arr[0]/3;
Return the array to main
return arr;
}

Tip: you simply need to write a for loop to go over the length of the sequences, pick a letter from each position,and, compare the two sequences position by position for matches and report the mismatches.
Answer:
Following are the code to the given question:
def match_sequence(s1,s2):#Defining a method match_sequence that accepts two parameters
for l in range(len(s1)):#defining a loop that checks range of s1 value
if(s1[l] != s2[l]): # use if block to match each sequences
print('The sequence does not match at index: ',l+1)#print value with message
s1 = 'CATCGTCCT'#defining a string varible s1
s2 = 'CACCGACCG'#defining a string varible s1
match_sequence(s1,s2)#calling a method that prints its values
Output:
The sequence does not match at index: 3
The sequence does not match at index: 6
The sequence does not match at index: 9
Explanation:
In this code, a method "match_sequence" is declared that takes two string variable "s1 and s2" in its parameters, and inside the method, a loop is declared that checks the range of s1 value and use if block to match each sequence and use a print method that prints it values.
Outside the method, two string variables are declared that holds a string value that passes into the "match_sequence" method and calls it.
What is output? public class MathRecursive { public static void myMathFunction(int a, int r, int counter) { int val; val = a*r; System.out.print(val+" "); if (counter > 4) { System.out.print("End"); } else { myMathFunction(val, r, counter + 1); } } public static void main (String [] args) { int mainNum1 = 1; int mainNum2 = 2; int ctr = 0; myMathFunction(mainNum1, mainNum2, ctr); } }
a) 2 4 8 16 32 End
b) 2 2 2 2 2
c) 2 4 8 16 32 64 End
d) 2 4 8 16 32
Answer:
The output of the program is:
2 4 8 16 32 64 End
Explanation:
See attachment for proper presentation of the program
The program uses recursion to determine its operations and outputs.
The function is defined as: myMathFunction(int a, int r, int counter)
It initially gets the following as its input from the main method
a= 1; r = 2; counter = 0
Its operation goes thus:
val = a*r; 1 * 2 = 2
Print val; Prints 2
if (counter > 4) { System.out.print("End"); } : Not true
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 2; r = 2; counter = 1
val = a*r; 2 * 2 = 4
Print val; Prints 4
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 4; r = 2; counter = 2
val = a*r; 4 * 2 = 8
Print val; Prints 8
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 8; r = 2; counter = 3
val = a*r; 8 * 2 = 16
Print val; Prints 16
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 16; r = 2; counter = 4
val = a*r; 16 * 2 = 32
Print val; Prints 32
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 32; r = 2; counter = 5
val = a*r; 32 * 2 = 64
Print val; Prints 64
if (counter > 4) { System.out.print("End"); } : True
This prints "End"
So; the output of the program is:
2 4 8 16 32 64 End
A list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor.

b. False
Imagine that you are helping to build a store management system for a fast food restaurant. Given the following lists, write a program that asks the user for a product name. Next, find out if the restaurant sells that item and report the status to the user. Allow the user to continue to inquire about product names until they elect to quit the program.
Answer:
The program in python is as follows:
def checkstatus(food,foodlists):
if food in foodlists:
return "Available"
else:
return "Not Available"
foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]
for i in range(len(foodlists)):
foodlists[i] = foodlists[i]. lower()
food = input("Food (Q to quit): ").lower()
while food != "q":
print("Status: ",checkstatus(food,foodlists))
food = input("Food (Q to quit): ").lower()
Explanation:
The program uses function.
The function is defines here. It accepts as input, a food item and a food list
def checkstatus(food,foodlists):
This check if the food is in the food lists
if food in foodlists:
Returns available, if true
return "Available"
Returns Not available, if otherwise
else:
return "Not Available"
The main begins here.
The food list is not given in the question. So, I assumed the following list
foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]
This converts all items of the food list to lowercase
for i in range(len(foodlists)):
foodlists[i] = foodlists[i]. lower()
Prompt the user for food. When user inputs Q or q, the program exits
food = input("Food (Q to quit): ").lower()
This is repeated until the user quits
while food != "q":
Check and print the status of the food
print("Status: ",checkstatus(food,foodlists))
Prompt the user for another food
food = input("Food (Q to quit): ").lower()

Using the algorithm/algorithmic environment, give pseudocode using recursion.Answer[[XXX TODO:your answer here]]4. What is the loop invariant of your second algorithm
Answer:
Following are the Pseudo Code to the given question:
Explanation:
Following are the pseudo-code by using the For loop:
Defines the A function (node, element)
The node is larger than 0.
if another value of the node equals its element
Loop Break
That element if node. value becomes lower than that
Node is node equivalent.
right
Using other nodes is node equivalent.
left
Node Return
If the node is vacant
print the Tree is empty
Following are the pseudo-code by using the while loop:
Defines the function A(node,element)
While this node is not zero.
if the value of the node equals the element
Loop Break
The element if node. value is lower than
Node is node equivalent.
right
Using other nodes is equivalent to an a.left node
Node Return
If the node is vacant
print Tree is empty
following are the Pseudo-code for recursion:
Set the function A (node, key)
If no root is the same as the root or no root.
return the root.
If the root value is lower than that of the quest for key return (root. right, key)
Return your lookup (root.left,key)
You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts.
You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed. You will not get any points unless you use pointers.

In the recursive function findMatch(), the first call is findMatch(array, 0, 4, key) . What are the remaining function calls to find the character 'e'?
public class FindMatch {
public static int findMatch(char array[], int low, int high, char key) {
if (high >= low) {
int mid = low + (high - low) / 2;
if (array[mid] == key) {
return mid;
}
if (array[mid] > key) {
return findMatch(array, low, mid, key);
}
else {
return findMatch(array, mid + 1, high, key);
}
}
return -1;
}
public static void main(String args[]){
char array[] = {'a','b','c','d','e'};
char key = 'e';
int result = findMatch(array, 0, 4, key);
if (result == -1) {
System.out.println("Element not found!");
}
else {
System.out.println("Element found at index: " + result);
}
}
}
a. (array, 2, 4, key) and (array, 3, 4, key)
b. (array, 2, 4, key), (array, 3, 4, key) and (array, 4, 4, key)
c. (array, 3, 4, key)
d. (array, 3, 4, key) and (array, 4, 4, key)
Answer:
The answer is "Option D".
Explanation:
In the given question "(array, 3, 4, key) and (array, 4, 4, key)", the element 'e' to also be searched is concentrated mostly on the right-hand side of the array since it is in the last place. This same middle value is 2 but findMatch(array, mid + 1 high, key) is labeled twice to move the center pointer to its last position, that is, so move that search item's 'e.'

The following Mic1 microcode excerpt shows support for a possible 7 bit opcode, 8 bit integer argument machine instruction (organized like the INSP instruction). This part of the microcode will be reached after the instruction opcode has been parsed and identified by earlier parts of the microcode and while the IR contains the complete instruction from memory (as usual for the IR).
100:a := band(smask, ir);
101:a := a + (-1); if n goto 0;
102:ac := lshift(ac); if n goto 104;
103:goto 101;
104:ac := ac + 1; goto 101;
