Introduction

In the previous chapter, we explored asymptotic analysis and the concept of Big O notation as a tool for analyzing the growth rate (How fast the running time grows as input size increases) of a function. In today’s chapter, we will explore our first data structure — Arrays.

Arrays

Arrays are one of the most basic and essential data structures. They store homogenous (same type) data in contiguous (adjoining) blocks of memory. The elements typically of the same type are stored in a linear and organized manner. This creates a clear and orderly relationship between the elements in the array.

Arrays provide quick access to elements based on their index, making them ideal for use cases that require random access. However, their fixed size can limit…
