why i am getting SIGSEGV error...problem code walk(practice easy)?

#include<stdio.h>
int main()
{
int arr[1000],n,j,max=0,m,i;
scanf("%d",&i);
while(i–)
{
scanf("%d",&n);
scanf("%d",&max);
arr[0]=max;
for(j=1;j<n;j++)
{
scanf("%d",&arr[j]);
if(max<arr[j])
max=arr[j];
}
m=max;
for(j=0;j<n;j++)
{
// printf("\t%d %d",max,j);
if(max<arr[j])
{
//j=0;
j=-1;
m++;
max=m;
// printf(“uu-%d”,max);
continue;

     		}
			max--;
		
		}
		printf("%d\n",m);
		max=0;
  	}
  	return 0;
}

Please provide link to the problem

An also either format your code properly, or just give an ideone link :confused:

Hi,
Look initially, you initialized the array with 1000 elements (int arr[1000])
and then when the compiler gets to

           for(j=1;j<n;j++)
	{
	        scanf("%d",&arr[j]);   
		if(max<arr[j])             this statement
		max=arr[j];
	}

look n value can get up to 10^5 but you have the arr(the array) with the size of 10^3. so it will overflow. so try fixing that I believe it’s the reason you getting runtime error.
Try initializing that array to int arr[100000].

Pay a closer attention to constraints next time. Index-out-bound exception is giving you runtime error, as kunnu rightly pointed out.
