// Question: decompose a positive integer into a prime factor. For example, enter 90 and print 90 = 2*3*3*5.// Program analysis: to decompose the prime factor of N, you should first find a minimum prime number k, and then follow the steps below to complete:// (1) if the prime number is equal to N, it indicates that the process of decomposing the prime factor is over. Print it out.// (
