I HAVE A DOUBT THIS PRINCIPLE USED IN ONLY DIVIDE BECAUSE IN THIS QUESTION we are just find those subarray which are divisible by n,but can we use it in when we require sum of array equal to N i.e. equal to size of array…
please briefly describe the question asked in video…

@AMIT_KUMAR you only have to find such subarrays whose sum is DIVISIBLE BY N, now if the sum is equal to N, then also it is divisible by N, right? I am not sure what is your doubt exactly so please elaborate a bit if this is not what you are asking.
