two-dimensional array

Two-dimensional array is a kind of array with special structure, which only converts each element in the original one-dimensional array into a one-dimensional array.

A two-dimensional array is similar in implementation to a matrix.

Storage of two-dimensional arrays:

For example: A two-dimensional array A=[[1, 2, 3], [2, 4, 5, 6], [1, 4, 6, 8]] The computer will also request a continuous space in memory and record the index position of the first array.

A[0][0]

In practice, the types of elements stored in an array are not necessarily the same, and different types of elements occupy different numbers of bytes.
