My issue

I was looking into some unsolved problems and my code is running just fine but it is not getting submitted only so please look into it.

My code

/* package codechef; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Codechef
{
	public static void main (String[] args) throws java.lang.Exception
	{
		// your code goes here
	    Scanner sc=new Scanner(System.in);
		int n=sc.nextInt();
		int cum_score_1=0;
		int cum_score_2=0;
		int max=0;
		int leader=0;
		for(int i=0;i<n;i++){
			int a=sc.nextInt();
			int b=sc.nextInt();
			cum_score_1+=a;
			cum_score_2+=b;
			if(Math.abs(cum_score_1-cum_score_2)>max){
				if(cum_score_1>cum_score_2){
					max=cum_score_1-cum_score_2;
					leader=1;
				}else{
					max=cum_score_2-cum_score_1;
					leader=2;
				}
			}
		}
		System.out.println((leader)+" "+max);
	}
}
