i'm trying to figure out how this solution works. for my solution, i tracked how long each robot had been waiting, to ensure their speed allowed them to go. in other words, if r2 speed is 5 and r1 speed is 11, r1 should attack twice before r2 goes again. so either i'm missing something or there were no test cases to account for this. thoughts?

Maybe this is just me, but I beat my head against a wall for an hour because I continuously failed the form id test case. After commenting that out I failed the input id test case. then the button id test case. I couldn't figure out what in god's name was wrong with my id's. Turns out I wasn't handling the "ref" properly. Nothing to do with the id's at all.
