The Boost C++ library in competitive programming
This post was originally written as a feature request for Codeforces; some relevant discussion can be found here. I believe that adding the Boost library on Codeforces would be a great addition for C++ competitive programmers. AtCoder already supports it (alongside GMP and Eigen, but Boost has replacements/wrappers for those: Boost.Multiprecision and Boost.uBLAS). CodeChef supports it too (or at least used to support it at some point, not sure now). I’ve seen at least 3 posts by people trying to use Boost on Codeforces and failing, and on thinking about it, I couldn’t really come up with a good reason (in my opinion) that Boost should not be supported on Codeforces....
