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;
}

Answer:
Design Process
Explanation:
The multistep process by which designers and engineers design, build, and taste a new product is called the Design Process. There are multiple steps, including exploring, designing, planning, making, testing, and revising.
Answer:
Explanation:
Because of the issues that have been sketched above, a number of other methods of project management have emerged in recent years. These methods are particularly suited for IT-development projects. Examples of these relatively new streams within project management include DSDM, RUP, eXtreme Programming (XP), RAD and agile project management (McConnell, 1996; Kroll, 2004; Chromatic, 2003; Stapleton, 2002, [ii], [iii])
Although the above-mentioned methods of project management differ according to a number of aspects, they are essentially the same. Because the path toward the final goal of IT projects has proved so uncertain, these methods assume that the goal will be achieved in a number of short cycles. This is the background for the term cyclical project management for these methods

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)
Denial-of-service - this is an attack which aims to deny users from accessing the content they want. a common example of this is flooding a server with spam requests, rendering it overloaded and unable to handle any user requests
