Write a function named show_twos that shows the factors of 2 in a given integer. For example, the following calls: 

show_twos(7);
show_twos(18);
show_twos(68);
show_twos(120);

should produce this output: 

7 = 7
18 = 2 * 9
68 = 2 * 2 * 17
120 = 2 * 2 * 2 * 15

The idea is to express the number as a product of factors of 2 and an odd number. The number 120 has 3 factors of 2 multiplied by the odd number 15. For odd numbers (e.g. 7), there are no factors of 2, so you just show the number itself. Assume that your function is passed a number greater than 0.
