The main principle of this code logic is one by one right shift the set bit of given number ‘n’ until ‘n’ becomes 0. Count how many times we shifted to make ‘n’ zero. The final count is position of the set bit. This is Simple and efficient way because bitwise operator take shorter time to execute than arithmetic operator.
