implement Math.clz32()

Question

Math.clz32() returns the number of leading zero bits in the 32-bit binary representation of a number.

Let's try to implement it by ourselves.

clz32(1) // 31
clz32(10000) // 18
clz32(25.45) // 27

Code

/**
 * @param {number} num
 * @returns {number}
 */
function clz32(num) {
  // your code here
}
