Given a binary array 'ARR' of size 'N', your task is to find the longest sequence of continuous 1’s that can be formed by replacing at-most 'K' zeroes by ones. Return the length of this longest sequence of continuous 1’s.

Asked in companies
You have been given an integer 'N'.
Your task is to return true if it is a power of two. Otherwise, return false.
An integer 'N' is a power of two, if it can be expressed as 2 ^ 'K' where 'K' is an integer.
For example:
'N' = 4,
4 can be represented as 2^2. So, 4 is the power of two, and hence true is our answer.
