WebApr 9, 2024 · The hamming distance between two integers is the number of bits which differ in them. To compute the hamming distance, we xor the two integers bitwise and count the number of bits set. This works because the xor yields 1 only when both bits are different. 1 hamming = lambda x,y: countSetBits(x ^ y) 1 2 >>> hamming(13, 11) 2 Explanation WebWelcome to TreeHacks!

WebThe idea is to use bitwise << and operators. Using the expression 1 << (k - 1), we get a number with all bits 0, except the k'th bit. If we do bitwise OR of this expression with n, i.e., n (1 << (k - 1)), we get a number which has all bits the same as n except the k'th bit which will be set to 1. For example, consider n = 20 and k = 4. WebDec 4, 2014 · Several months back, we posted link to Stanford bit twiddling website in Fastest Way to Reverse Complement a Sequence.
