I am trying to write a method that I can pass in two values (low number, high number) and will return a non-repeating random number within this range, one number at a time (possibly button click, not sure yet - I'll tackle that later). Once all available numbers are used, I want it to return a -1. I cannot move on until I get this tested functionally. I am trying to make use of a binary array to keep track of used numbers by index. Here is what I have so far:

Any ideas?

There are solutions to your problem.

I ended up setting a counter equal to the size of my array, then incrementing that counter each time through the loop - using that to index my boolean. It is satisfying
