C :

#include<stdio.h>
void main()
{
	int t,m,n;
	scanf("%d%d",&m,&n);
	t=(n-m)*30;
	printf("%d\n",t);

  }  

C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){

	int m,n;
	cin>>m>>n;
	cout<<(n-m)*30<<endl;
	


	return 0;
}

Pascal :

var
  a,n,m:longint;
  s:real;
begin
  read(n,m);
  a:=(m-n)*30;
  write(a);
end.

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		//获取两个整数m、n
		int m = sc.nextInt();
		int n = sc.nextInt();
		//定义旋转角度为i
		int i ;
		i = (n-m)*30;
		System.out.print(i);
	}
}

Python :

m,n=map(int,input().split())
if n-m!=0:
    s=(n-m)*30
if n-m==0:
    s=360
print(s)
