**Input and Output C++**

### Problem Statement :

Objective In this challenge, we practice reading input from stdin and printing output to stdout. In C++, you can read a single whitespace-separated token of input using cin, and print output to stdout using cout. For example, let's say we declare the following variables: string s; int n; and we want to use cin to read the input "High 5" from stdin. We can do this with the following code: cin >> s >> n; This reads the first word ("High") from stdin and saves it as string s , then reads the second word ("5") from stdin and saves it as integer n . If we want to print these values to stdout, separated by a space, we write the following code: cout << s << " " << n << endl; This code prints the contents of string s , a single space (" "), then the integer . We end our line of output with a newline using endl. This results in the following output: High 5 Task Read 3 numbers from stdin and print their sum to stdout. Input Format One line that contains 3 space-separated integers: a , b , and c. Constraints 1 < = a, b, c <= 1000 Output Format Print the sum of the three numbers on a single line.

### Solution :

` ````
Solution in C :
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
int main() {
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
int a,b,c;
cin>>a>>b>>c;
cout<<a+b+c;
return 0;
}
```

## Waiter

You are a waiter at a party. There is a pile of numbered plates. Create an empty answers array. At each iteration, i, remove each plate from the top of the stack in order. Determine if the number on the plate is evenly divisible ith the prime number. If it is, stack it in pile Bi. Otherwise, stack it in stack Ai. Store the values Bi in from top to bottom in answers. In the next iteration, do the

A queue is an abstract data type that maintains the order in which elements were added to it, allowing the oldest elements to be removed from the front and new elements to be added to the rear. This is called a First-In-First-Out (FIFO) data structure because the first element added to the queue (i.e., the one that has been waiting the longest) is always the first one to be removed. A basic que
