C :

#include<stdio.h>
int main()
{
    int x;
    scanf("%d",&x);
    if(x<=100)
        printf("%d",2*x);
    if(x>100)
        printf("%d",100+x);
        return 0;
}

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int s;
		if(n <= 100){
			s = 2 * n;
			System.out.println(s);
		}else if(n > 100){
			s = 2 * 100 + (n - 100) * 1;
			System.out.println(s);
		}
	}

}

Python :

n = int(input())
if n <= 100:
    m = n * 2
else:
    m = (n - 100) * 1 + 2 * 100
print(m)
