$5.$ Write a Python Program that asks the user to enter two non$-$negative numbers

and find the sum of all integers between and including the numbers.

If the user enters a negative number, the program will display a message to the

user and ask the user to enter a non$-$negative number. This process will repeat

until the user enters the correct number. If the user enters the correct number,

the program will display the two numbers and continue.

Finally, the program should find the sum of all integers between the two numbers,

inclusive $(10$ pts$).$

Sample inputs and outputs

Inputs:

Enter the starting number: $-4$

The starting number cannot be negative.

Enter the starting number: $2$

Enter the ending number: $0$

The ending number cannot be zero.

Enter the ending number: $8$

Output:

The sum of all numbers between $2$ and $8$ is $35$

Variables: start, end, total, etc
