I had this function working before, until my teacher told me to "make it more flexible", in which I pretty much revamped the project and couldn't fix the function. My problem is that the ints great1 and great2 output their values as rounded to the lower number, which makes the if statement always false (=bool equality). However, the code then reads the bool equality as true, which is not always the correct answer.

Can anyone help? This would help me solve two other functions.
