Problem Statement - link #

CodeChef recently revamped its practice page to make it easier for users to identify the next problems they should solve by introducing some new features:

• Recent Contest Problems - contains only problems from the last 2 contests
• Separate Un-Attempted, Attempted, and All tabs +Problem Difficulty Rating - the Recommended dropdown menu has various difficulty ranges so that you can attempt the problems most suited to your experience
• Popular Topics and Tags

Our Chef is currently practicing on CodeChef and is a beginner. The count of ‘All Problems’ in the Beginner section is X. Our Chef has already ‘Attempted’ Y problems among them. How many problems are yet ‘Un-attempted’?

Input Format:

• The first and only line of input contains two space-separated integers X and Y — the count of ‘All problems’ in the Beginner’s section and the count of Chef’s ‘Attempted’ problems, respectively.

Output Format:

Output a single integer in a single line — the number of problems that are yet ‘Un-attempted’.

Examples #

Example 1:

Input :
10 4

Output :
6

Explanation :
Test Case 1: There are 10 problems in total in the Beginner's section, out of which 4 have been attempted. Hence, there are 6 Un-attempted problems.

Constraints #

• 1 ≤ Y <= X ≤ 1000

Solutions #

#include <iostream>
#include <bits/stdc++.h>
using namespace std;

typedef long long ll;
int MOD = 1e9+7;

int solution(int x, int y) {
    return abs(x-y);
}

int main() {
	// your code goes here
	int T; 
// 	cin >> T;
    T = 1;
	int x,y;
	while(T--) {
	    cin >> x >> y;
	    auto res = solution(x,y);
	    cout << res << endl;
	}
	return 0;
}
