In recent days, there’s been a question coming up on twitter: how do you find the second largest element in an array (container)? People are providing different answers. As usual, there are multiple solutions to this problem and they depend on the actual requirements: could this operation have side effect (change the original range) or should it be left untouched? In this post, I will discuss several solutions in C++ to this problem.
