There are $n$ patients in an hospital (let's call them $p_1 \dots p_n$), each of them need an operation of by $n$ different doctors (let's call them $d_1 \dots d_n$) -- so $n^2$ o...

I made this code series for my computer science friends--they had fun solving it, and one of them told me I should put it up in this site, so here goes. The end of the code is rather unexpected!
Each code has clue for the next one--the first code is easy so that shouldn't be a problem. (if you re...
