Explanation:
A friend of Alex has gifted a movie collection, and Alex is excited to watch them all as quickly as possible. The duration of the movies is given in array durations[n], where n is the number of movies, and each movie duration lies between 1.01 and 3.00 units of time (up to two decimal places). Every day, Alex wants to spend no more than 3.00 units of time watching the movies but also wants to complete the movies in the least number of days possible. Alex does not leave a movie in between. That is, if Alex has picked up a movie, Alex watches the complete movie on the same day. Find the minimum number of days needed to watch all the movies.
To find out the duration of alex's movies, you can use the code in C++ to make this calculation, where you will only need the number of movies and their duration, as well:
Writing code in C++:#include<bits/stdc++.h>
using namespace std;
struct Movie {
int timeBegin, duration, timeEnd;
bool operator<(const Movie& another) const {
return timeEnd < another.timeEnd;
}
};
struct Festival {
int count;
vector<Movie> movies;
};
Festival* initialize(int timeBegin[], int duration[], int count) {
Festival* filmFestival = new Festival;
filmFestival->count = count;
for (int i = 0; i < count; i++) {
Movie temp;
temp.timeBegin = timeBegin[i];
temp.duration = duration[i];
temp.timeEnd = timeBegin[i] + duration[i];
filmFestival->movies.push_back(temp);
}
return filmFestival;
}
int solve(Festival* fest) {
int res = 0;
sort(fest->movies.begin(), fest->movies.end());
int timeEnd = -1;
for (int i = 0; i < fest->count; i++) {
if (fest->movies[i].timeBegin >= timeEnd) {
res++;
timeEnd = fest->movies[i].timeEnd;
}
}
return res;
}
int main(int argc, char *argv[]) {
int timeBegin[] = {1, 3, 0, 5, 5, 8, 8};
int duration[] = {3, 2, 2, 4, 3, 2, 3};
Festival * fest;
fest = initialize(timeBegin,duration, 7);
cout << solve(fest) << endl;
return 0;
}

What do you prevent when you use data validation in your database forms?
O code injection
O phishing
O botnet
O denial-of-service
Answer:
code injection
Explanation:
Validating the data in a database prevents someone from sneaking code to run without permission, aka code injection.
Phishing - this is disguising as a reputable company/person and trying to steal info (passwords, credit card numbers)
Botnet - this is a network of computers (most likely in the network because of a virus) that are used as a group for malicious purposes (like spam)
