using namespace std;

int main() {
int t;
cin>>t;
while(t–)
{
int n,arr[1000],ct=0;
cin>>n;
for(int i=0;i<n;i++)
{
cin>>arr[i];
}
for(int i=0;i<n;i++)
{
if(i==0 && arr[i+1]==0 && arr[i]==0)
{
ct++;
}
else if(i==n-1 && arr[i-1]==0 && arr[i]==0)
{
ct++;
}
else if( i>0 && arr[i]==0 && arr[i+1]==0 && arr[i-1]==0)
{
ct++;
}

    }
    if(ct>0)

        cout<<ct<<endl;
    }

// your code goes here
return 0;

Consider the testcase:

6
000110

(the answer should be 2).

Based on your screenshot, you’ve added spaces between all the 0’s and 1’s in the testcase I gave you, for some reason.

Corrected code.^

how did your code work for n = 2 cases? wouldn’t count be incremented twice?

Example?
It goes in the bottom part only when n is 1. Otherwise it just does whatever your code does.

say i enter 00, wouldn’t count become 2?

Yes?, it’s supposed to be 2.
