back to boardWhat's the difference btween -1 and m-1? Posted by LNCP 7 Feb 2015 18:38 It's obvious we calculate recurrence with Matrix.But in the base Matrix,I first used -1,then I got WA#3,while I replaced it with m-1,I got AC.Who can explain it to me?

If you mean +1, then makes Fibonacci sequence. But problem not Fibonacci, although similar idea.
When use m - 1 to replace +1, makes problem's recurrence |
