Solutions to UVa Online Judge

My solutions to the problems in http://uva.onlinejudge.org - my username is bruceoutdoors.

I rate them accordingly (bear in mind this is only my opinion and might not reflect how hard/easy the problem actually is):

• Super easy (quick to solve, without putting much thought/planning)
• Easy (think a bit, but won't strain you too much)
• Quite easy (helps to write it down and go through it in your head first; you're not likely to get it right the first time)
• Intermediate (will need to crack your head a bit, but with some effort you can solve it)
• Challenging (not a straighforward solution; requires some esoteric knowledge, and not likely to solve in a day)
• Advanced (even experienced coders/lecturers might have trouble figuring it out)
• Insane (for algorithm experts or crazy geniuses only)

Problems are sorted in order which they were solved, decimals in bold are the fastest run times. Problems marked with '*' have READMEs:
