'''A 2D array, also known as a two-dimensional array, is a data structure that stores elements in a grid or matrix-like fashion with rows and columns. It can be thought of as an array of arrays, where each element in the array is itself an array. In programming, 2D arrays are often used to represent tables, matrices, or grids of data.'''
