The smaller types exist mainly to allow RAM usage optimization for arrays and structs. In most cases they trade a few CPU cycles (in the form of aligment operations) for a better RAM usage.
Unless you need to enforce your return value to be a signed or unsigned number of a centain size (cha...
Negative weights using Dijkstra's Algorithm
...so that a vertex cannot be enqueued more than once (e.g., using a marked[] array to mark those vertices that have been relaxed), then the algorithm is guaranteed to run in E log V time but it may yield incorrect results when there are edges with negative weights.

Python Linked List
...ne practical advantage of a singly linked list over doubly linked lists or arrays (which Python uses internally for lists) is that two linked lists can share a tail. This is very useful for dynamic algorithms that require saved values from previous iterations where sharing list tails can reduce mem...
