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
code: function minOperations ( S , K ) { var ans = 0 ; for ( var i = 0 ; i < K ; i ++ ) { var zero = 0 , one = 0 ; for ( var j = i ; j < S . length ; j += K ) { if ( S [ j ] === " " ) zero ++ ; else one ++ ; } ans += Math . min ( zero , one ) ; } return ans ; } var S = " " ; var K = 3 ; document . write ( minOperations ( S , K ) ) ;
