WebOriginally, only vector, list and deque were defined. Until the standardization of the C++ language in 1998, they were part of the Standard Template Library (STL), published by SGI. Alexander Stepanov, the primary designer of the STL, bemoans the choice of the name vector, saying that it comes from the older programming languages Scheme and Lisp but … WebMar 21, 2024 · Dynamic Programming is mainly an optimization over plain recursion. Wherever we see a recursive solution that has repeated calls for same inputs, we can optimize it using Dynamic Programming. The idea is to simply store the results of subproblems, so that we do not have to re-compute them when needed later.
