Ah yes I can see it now. Thank you both for the answers.

I am teaching a course on the ACSL competition to middle school students and my programming skills are little rusty. In the next competition we have a programming challenge where they need to create a program that you can input a string and several substring parameters. The problem is that they need to be able to input a negative number and have it produce the desired result. For example:

with the string "Hello world!"

input 1: 0, -1 output 1: Hello world

input 2: 0,-5 output 2: Hello w

input 3: -4,0 output 3: rld!

I am at a little bit of a loss as how to go about getting the desired output.
