Arrays are one of the most basic data structures

An array is a data structure that contains a group of elements. The most basic implementation of an array is a static array, in which the array has a fixed size that must be declared when it is initialized. In technical interviews, you’re also going to come across questions about dynamic arrays (similar to static arrays, but with space reserved for additional elements) and multidimensional arrays (arrays in which the individual elements are also arrays).
