Minimize flips on K | .
We 're flipping the subarray from  A[i] to A[i+K-1].
' ' ▁ If ▁ we ▁ can ' t flip the entire subarray , its impossible.
Driver Code"
How can the above be solved in Python?

#Here is code to minimize flips on K and the other steps required.

		if ( A [ i ] == flip ) :
			count += 1

			flip ^= 1
			if ( i + K < len ( A ) ) :
				temp [ i + K ] ^= 1
