Silver
About
Here you can find the solutions to the past problems from the Silver Division since December 2015, with most of the work still being in progress as I add the files here.
Among topics most commonly given in the silver division, we can mention greedy algorithms, binary search, graph traversals, flood fill as well as math problems. Ad hoc problems are also more and more frequent especially in the last few years.
In the future I plan adding more past solutions as I work through them.
