Python Challenges - 1: Exercise-3 with Solution

Write a Python program to check if a given positive integer is a power of four.

Explanation:

Python: A positive integer is a power of 4

Sample Solution:

Python Code :

def is_Power_of_four(n):
    while n and not (n & 0b11):
        n >>= 2
    return (n == 1)

print(is_Power_of_four(4))
print(is_Power_of_four(16))
print(is_Power_of_four(255))

Sample Output:

True
