Can anyone tell what’s wrong in this code?

  #include<bits/stdc++.h>
    using namespace std;
    int main() {
        int a;
         int b,min=0;
        cin>>a;
        while(a--){
            cin>>b;
            int s[b];
            for(int i=0;i<b;i++)
                cin>>s[i];
            sort(s,s+b);
            min=s[1]-s[0];
            for(int i=1;i<b;i++){
                if((s[i+1]-s[i])<min)  
                    min=s[i+1]-s[i];
            }
            cout<<min;
        }
    }

Out of bounds error on the line if((s[i+1]-s[i])<min):

#include <stdio.h>
#include <stdlib.h>

int main(void) {
int t;
scanf("%d",&t);
while(t–){
long long int n,x;
int y=10000000;
scanf("%lld",&n);
int arr[n];
for(int i=0;i<n;i++){
scanf("%lld",&arr[i]);}

    for(int k=0;k<n;k++){
        for(int j=k+1;j<n;j++){
        x=abs(arr[k]-arr[j]);
        if(y>x){
            y=x;
        }
    }
}

printf("%lld\n",y);
}
return 0;
}
why this is a wrong approach ,its give me right ans but when i am submitting it ,it shows that it is wrong .please help me.

Please either format your code or (better!) link to your submission - the forum software has mangled it and it won’t compile! :slight_smile:

Edit:

Consider the test input:

1 1000000000
