2-Dimensional Arrays

A 2-dimensional array is an array of arrays where each element is itself an array. It allows for the organization of data in rows and columns, creating a grid-like structure.

A 2-dimensional array is used to represent tabular data or grids in programming, allowing for efficient storage and manipulation of data in rows and columns.

A 2-dimensional array has an additional dimension, allowing for the storage of data in rows and columns, while a 1-dimensional array stores elements in a single linear sequence.

Some advantages of using a 2-dimensional array compared to a 1-dimensional array include the ability to represent tabular data more efficiently, simplify complex data structures, and facilitate matrix operations in mathematical computations.

In row-major order, the elements of each row are stored together in memory, allowing for efficient traversal of rows, while in column-major order, the elements of each column are stored together, enabling efficient traversal of columns.

Flattening a 2-dimensional array into a 1-dimensional array involves concatenating all the rows or columns into a single sequence, while converting a 1-dimensional array into a 2-dimensional array requires reshaping the array into the desired row and column dimensions.
