Algorithmic Learning (12)
1.Integer Factorization
Description: The basic theorem of the algorithm is that any integer can be expressed as the product of one or more prime numbers, such a representation is unique, for example:
1000 = 2 * 2 * 2 * 5 * 5 * 5
1001 = 7 * 11 * 13
1002 = 2 * 3 * 167
1003 = 17 * 59
1009 = 1009
Problem statement:
You'll get a few numbers and de ...
