Given a integer N, with prime factorisation n1p1 * n2p2 …… The task is to check if the integer N is power-isolated or not.
An integer is said to be power-isolated if n1 * p1 * n2 * p2 ….. = N.
Input: N = 12 Output: Power-isolated Integer. Input: N = 18 Output: Not a power-isolated integer.
Approach: For an integer to be power-isolated the product of its prime factors and their power is equal to integer itself. So, for calculating same you have to find all prime factors of the given integer and their respective powers too. Later, calculate their product and check whether product is equal to the integer or not.
- Find the prime factor with their factor and store them in key-value pair.
- Later calculate product of all factors and their powers.
- if product is equal to integer, print true else false.
Below is the implementation of the above algorithm:
Power-isolated Integer Not a Power-isolated Integer Power-isolated Integer
