Decrement OR Increment | Codechef solution
Problem of Decrement OR Increment | Codechef solution:-
Write a program to obtain a number N
N
and increment its value by 1 if the number is divisible by 4 otherwise
otherwise
decrement its value by 1.
Input of Decrement OR Increment | Codechef solution:
- First line will contain a number N
.
Output:
Output a single line, the new value of the number.
Constraints
- 0≤N≤1000
Sample Input:
5
Sample Output:
4
EXPLANATION:
Since 5 is not divisible by 4 hence, its value is decreased by 1.
Code:-
#include <iostream> using namespace std; int main() { int n; cin>>n; if(n%4==0) cout<<n+1; else cout<<n-1; return 0; }
