For this assignment you will want to create $2$ files called "RunMyMethods" and $$MyMethods$$ The first file $$RunMyMethods$$ will contain the main that calls a menu method and will have a loop structure that will allow a user to choose what program they want to run. The menu displayed will look like this:

$1)$ Product no negatives

$2)$ Find Twelve

$3)$ Max Min Avg

$4)$ Letter Grade

$5)$ Custom Method $($ you design and name$)$

$6)$ Exit

The second file $$MyMethods$$ will have methods in it that correspond to the menu shown above. The methods should do the following:

$1.$

Write a program that will find the product of a collection of data values. The program should ignore all negative values, not convert negative values to positive. For Example if I enter in $2-34$ the answer would be $8$ not positive $24.$

$2.$

Write a program to read in a collection of integer values, and find and print the index of the first occurrence and last occurence of the number $12.$ The program should print an index value of $0$ if the number $12$ is not found. The index is the sequence number of the data item $12.$ For example if the eighth data item is the only $12,$ then the index value $8$ should be printed for the first and last occurrence.

$3.$

Write a program to find the minimum, maximum, and average values of a collection of data values. The number of data values is unspecified.

$4.$

Write a program to read in a collection of exam scores ranging in value from $0$ to $100.$ The program should count and print the number of A$\text{'}$s $(90$ to $100),$ B$\text{'}$s $(70$ to $89),$ C$\text{'}$s $(50$ to $69),$ D$\text{'}$s $(35$ to $49)$ and F$\text{'}$s $(0$ to $34).$ The program should also print each score and its letter grade. The following is an example of test data you could enter, but feel free to enter any data you like:

$637572727867806309089435999821210075$

Think of a creative method that you can do for yourself. Calculating baseball averages, golf handicaps, or a fortune teller app based on your fa
