C :

#include<stdio.h>
int main(){
      int   a,b;
      scanf("%d %d", &a,&b);
      int  max = a;
      if(b>max) {
       max = b;
       }
      printf("%d",max);
   

     return 0;
}

C++ :

#include<iostream>
using namespace std;
int main(){
	int x;
	int y;
	cin>>x>>y;
	if(x>y){
		cout<<x<<endl;
	}else{
		cout<<y<<endl;
	}
}

	

Python :

a , b = map(int,input().split());
if a > b:
    print(a)
else:
    print(b)
