What is a code to find smallest positive number Y such that Bitwise AND of X and Y is Zero and the other steps required given the following:
Find smallest positive number Y such that Bitwise AND of X and Y is Zero | Method to find smallest number Y for a given value of X such that X AND Y is zero.
Convert the number into its binary form.
Case 1 : If all bits are ones , then return the next number.
Case 2 : find the first 0 - bit index and return the Y.
