Casting unsigned int to signed int reduces stack memory usage, but why?
Today, I was checking the official solution for problem grassplant of USACO 2011 December Contest. I ran the solution on 12th test and it gave me runtime error (segmentation fault). I realized it was caused by stack overflow. Then (somewhy) I added (int) before E[u].size() in the function hang() and ran it on 12th test again. Surprisingly, stack did not overflow this time.
Can anyone who gets this stuff tell why this happens?
