ct++;
}
else if(i==n-1 && arr[i-1]==0 && arr[i]==0)

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

Consider the testcase:

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.^

24

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

25

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

26

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

27

Yes?, it’s supposed to be 2.
