text: Minimum flips required to convert given string into concatenation of equal substrings of length K | Function that returns the minimum number of flips to convert the s into a concatenation of K - length sub - string ; Stores the result ; Iterate through string index ; Stores count of 0 s & 1 s ; Iterate making K jumps ; Count 0 's ; Count 1 's ; Add minimum flips for index i ; Return minimum number of flips ; Driver code
