Minimize flips to make binary string as all 1 s by flipping characters in substring of size K repeatedly | Function to find the minimum number of operations required to convert all the characters to 1 by flipping the substrings of size K.
Stores the minimum number of operations required.
Traverse the string S.
If the character is 0.
Flip the substrings of size K starting from i.
Increment the minimum count of operations required.
After performing the operations check if string S contains any 0 s.
If S contains only 1 's.
