Write a program to enter a natural number n and find all sphenic numbers from 1 to n using Recursion (combined with iteration if necessary). Note: A sphenic number is a product of p*q*r where p, q, and r are three distinct prime numbers. Example: 30 = 2 * 3* 5; 42 = 2*3*7; 66 = 2*3*11. 30, 42, 66, 70, 78, 102, 105, 110, 114, 130, 138, 154, 165, … are sphenic numbers.
