Data Structures – Trees Up until this point we looked at only linear data structures. Now it’s time for trees, which are a hierarchical. This means that the elements contained in the tree are in a hierarchy and each element can have multiple subordinate elements. They are used all over the web, html code is […]

Data Structures – Stacks and Queues Next data structure we’ll look at are stacks and queues. They are both linear data structures and they follow specific rules for insertion and deletion of elements. Definition Stacks are FILO (First in Last Out) or LIFO ( Last In First Out). This means that the first element you

Data Structures – Hash Tables Hash tables are containers of key and value pairs. Each key is unique and is mapped to some value. Hash Tables use a hash function to compute an index, hash code, and store that pair into a slot of some reserved part in memory. Hash tables are widely used because

Data Structures – Linked Lists Linked lists are probably the simplest data structure of all. They are just nodes, containing some data and a reference to the next node in the list, all nodes are linked to one other node and they form a sequence or a list. This is the most basic form, we’ll

DATA STRUCTURES – ARRAYS An array is the simplest and most used data structure we’ll cover in this guide. It’s a collection of items stored at contiguous memory locations. There are a few types of implementation based on what language you’re using, some are static, some are dynamic, some an store multiple types of data,
