1.Suppose you want to develop a program for a first-grader to practice subtraction.

The program randomly generates two single-digit integers, number 1 and number 2

Example: It displays to the student a question such as "What is 9 - 2?" After the student enter the answer, the program displays a message indicating whether it is correct.

Specifically, the program can work as follow:

1.Generate two single-digit integers into number1 and number2

2.If number1 < number2, swap number1 with number2

3.Prompt the student to answer, "What is number1 - number2?"

4.Check the student's answer and display whether the answer is correct
