Problem $3(10$ points$)$

Remember waaaay back in homework $2$ when you wrote an algorithm for sorting Dr$.$ Harper's

horde collection of buttons? After almost an entire semester of learning MATLAB, she knows

you're ready to tackle writing the sorting code. You might want to start by revisiting $($and

potentially revising$)$ your algorithm.

The file HW$13$ buttons $.$ txt contains a list of buttons to sort. The information for each

button is formatted as a string of length $3$ with information on its number of holes, shape, and

color. The first character is the number of holes, the second is the shape, and the third is the

color. For example, a circular, blue button with $2$ holes is $2cb.$ Below is a list of characteristics

and their corresponding character:

The last line of the file is a single # to indicate the end of the file.

Requirements:

Read the data in using fscanf

Your code must be able to accept a list of buttons of any length

Every button's information will be formatted the same way, we promise!

Your code should include at least one user$-$defined function $($more is OK$.)$

Send to the screen a text summary of the number of buttons with each of the $9$

characteristics listed above so Dr$.H$ can compare the amount of buttons in each category.

It is fine to refer to the categories by their single$-$character designations.

The code should prompt a user to enter the $3-$character string associated with a particular

kind of button $($e$.$g$.,2$cb$)$ and tell the user how many of that button there are in the

collection.
