Calculate Log2n without using built-in function
Objective: Given a number n, write a program to calculate Log2n without using built-in function.
N = 32 Log232 = 5 N = 64 Log264 = 6
- Initialize result = 0.
- Keep dividing the given number by 2 till number is greater than 0 and add one to the result if n is greater than equal to 1.
Log64 value: 6
