A program is comprised of data and algorithms. Algorithms tell us how the data will be transformed. Adding structure to data can make algorithms simpler, easier to maintain, and often faster.
Once an item is added, it stays in that position relative to other elements that came before or after it. Examples include stacks, queues, dequeues, lists.
Not being a CS student, needed to learn about basic data structures. This repo contains some basic python codes I came up with while learning data structures.
