June challenge COVDSMPL question getting TLE with time = -1.00 sec

plz, tell me why was I getting -1.00 sec. if it was TLE with 1.01 sec then we know it is beyond the time limit but why -1.00 sec.

question link:https://www.codechef.com/JUNE20B/problems/COVDSMPL/

my code:

#include <iostream>
using namespace std;

int main() {
	// your code goes here
	int t;
	scanf("%d",&t);
	int N,P,i,j,X;
	int arr[60][60]; 
	while(t--)
	{
        	    
        	    scanf("%d%d",&N,&P);
        	    
        	    
        	    for(i=1;i<=N;i++)
        	    {
        	        int max=0;
        	        for(j=1;j<=N;j++)
        	        {
        	            int al=1;
        	            int r1=i,r2=i,c1=1,c2=j;
        	             printf(" %d %d %d %d %d\n",al,r1,c1,r2,c2);
        	             scanf("%d",&X);
        	             if(X==-1)
        	             _Exit(10);
        	             else
        	             {
        	                 if(X>max)
        	                 {
        	                 arr[i][j]=1;
        	                 max=X;
        	                 }
        	                 else
        	                arr[i][j]=0;
        	       
        	             }
        	        }
        	    }
        	     printf("2\n");
        	     
        	    for(i=1;i<=N;i++)
        	    {
        	        for(j=1;j<=N;j++)
        	        {
        	            printf("%d ",arr[i][j]);
        	        }
        	        printf("\n");
        	    }
        	   scanf("%d",&X);
        	   if(X==-1)
        	   _Exit(0);
    }
	
	return 0;
}

TLE(-1.0000) means that your idle time limit is exceeded

you are not taking input/ giving output at the right time intervals

yes you are right it means that but if you see my code i am taking and giving all the input and output.please if you see my code and tell me where I went wrong it would be a great help.

:cry:
actually i don’t code in C++ (I’m beginner and just started CS in school :sweat_smile:)
so, i won’t be of much help there sorry

You aren’t flushing your output. Try to use fflush(stdout) after every query and before taking any input.

bro ,you are printing a space before %d after the line int r1=i,r2=i,c1=1,c2=j, u should start with a number.

This isn’t necessary.

i started with a no at first but i thought of this but both were having same result.I am really confused bro.

One more thing that I found was u have declared int arr[60][60],
and since it is 0 based index, U should have declared arr[61][61]. And why exit_(10) and not 0,
By the way ,even if you correct tle, you will get wa, because your 1st element of each row isnt necessarily correct.
