This category is for logical grouping only. It needn’t to be added directly. Instead, the sub-categories should be added.

Stacks have a wide range of uses in algorithms, for example in language parsing and runtime memory management (“call stack”). A short and beautiful algorithm using a stack is depth-first search (DFS) on a tree or graph data structure. Python ships with several stack implementations that each have slightly different characteristics.
