Sure! In Rust, you can create a multidimensional array using nested square brackets. Here's an example of how you can create a two-dimensional array:
let mut matrix: [[i32; 3]; 3] = [[0; 3]; 3];
In the above example, we've created a 2D array named matrix that has dimensions 3x3. The mut keyword indicates that the array is mutable and can be modified. Each element of the array is initialized to 0 using the [[0; 3]; 3] syntax. The [[0; 3]; 3] syntax creates a new array that contains three elements that are each an array of length 3, with all elements initialized to 0.
Now suppose you want to create a 3D array with dimensions 2x2x2, with each element initialized to 1. You can do that as follows:
let mut arr: [[[i32; 2]; 2]; 2] = [[[1; 2]; 2]; 2];
In the above example, we've created a 3D array named arr with dimensions 2x2x2. Each element of the array is an array of length 2, with each element of those arrays being a i32 value initialized to 1.
You can also access elements of the array using their indices. Here's how to access the element at row 1, column 2 of matrix:
matrix[1][2] = 42;
In this case, we're modifying the value of the element at row 1, column 2 of matrix to be 42. You can also use nested loops to iterate over the elements of a multidimensional array.
