Array Interview Questions (Plus Sample Answers)
A
dynamic array
is an array that automatically resizes itself when it runs out of space. It typically starts with a fixed-size array and, when it exceeds its capacity, creates a new larger array and copies the elements from the old array to the new one. This ensures that the array can grow as needed while maintaining an efficient allocation of memory.

An
array
is a data structure used to store multiple values in a single variable, which can be of the same or different types (depending on the programming language). Arrays are commonly used to organize data, store collections of items, and facilitate operations on a series of elements (such as looping through them, searching, or sorting).

A
multi-dimensional array
is an array that contains more than one index or dimension to store data. Unlike a one-dimensional array (which is essentially a list of elements), multi-dimensional arrays allow for the storage of data in a grid or matrix-like structure. They are often used to represent more complex data, such as tables, matrices, or even spatial data in scientific computing.
