Summary
This problem is funny. There are no tricks, and there are quite a few ways to "solve" this, and it's easy to code.

No explanations needed, simply follow the calculation, doing it recursively, figuring out a pattern, it doesn't get much easier than this! There is a shortcut way to solve this problem.That is if(n<=100) printf("f91(%d) = %d\n",n,91); if(n>=101) printf("f91(%d) = %d\n",n,n-10); --MD. JULKER NEYEN SAMPAD 02:29, 19 July 2014 (EDT)
