Hamming distance
Calculates the Hamming distance between two values.
- Use the XOR operator (
^) to find the bit difference between the two numbers. - Convert to a binary string using
Number.prototype.toString(). - Count and return the number of
1s in the string, usingString.prototype.match().
const hammingDistance = (num1, num2) => ((num1 ^ num2).toString(2).match(/1/g) || '').length; hammingDistance(2, 3); // 1
