Write a program that reads two integers. Verify whether num1 is greater than num2. If it isn't,
apply a swap operation using the algorithm described in Chapter 5.6, ensuring that num1 is
now larger than num2. Subsequently, create a list of numbers in descending order from num1
to num2, with intervals of 7.
EX: 162 190
190, 183, 176, 169, 162
EX: 12 22
22, 15
EX: 17 2
17, 10, 3
