Here are some problems I have completed at the Valladolid Programming Contest Problem Set. I was rather surprised to find that information about these problems is quite hard to find. So I am starting a collection of solutions here. I hope these solutions help some people out there who are struggling. I don't have the best solutions, but something is better than nothing! -PR

So here they are:

101.c by yatsen
102.cpp by PR - They call this a challenge.
103.cpp by PR
106.cpp by PR
107.cpp by PR - Using my number theory.
108.cpp by PR - Don't ask. My code for this problem is incomprehensible.
110.cpp by PR - Please be aware this is a multiple input problem and so don't waste two hours like I did and read how you're supposed to do multiple inputs.
111.cpp by PR
113.cpp by PR

In fact, if you have problems on any Volume I problem, just ask me.

Mail me at frinesispecial12@yahoo.com if you have any comments or suggestions or especially if you want to add on to the collection. Unless you want to be anonymous, I will list your name here if you submit a solution. Also, tell me if any of these do not work. To the best of my knowledge, they all should work.
