well people do way better than me but appreciate it

I had this happen using Java, creating a new int array instead of rewriting the data into the input array fixed it.

I feel like this is properly ranked, I will give you that it is a longer than a normal 7kyu but it's mainly manuipluating a string.

Yeah!! I ran into a similar issue of missing a key piece of information and started working things out by hand before I went back re-read the instruction.

I would say re-read the instructions, there is a key peice of information you are missing :). In the instructions is read the limits on what m can be; m has to be greater than n

edit: I added more info because it was in the instructions I decided it wasn't a spoiler.

It helps if I read the whole description "finds the first pair". Very good Kata!!!

I really enjoyed this Kata, it made me remember some formulas I haven't used in a long time!!

Yes, you are correct. I was going to put an extra check for that specific case but it ended up not being needed with the test given. I was trying to keep my solution as short as possible.

Print out the results and think about why you are getting that number!

This was a really good Kata, it took about 3 pages of scratch paper to figure out how I wanted to do this!!

I just wanted to say I really enjoyed this Kata! Very well put together!
