In this section, we will create a Java program to rotate a matrix by 90 degrees in a clockwise and anti-clockwise rotation. The clockwise rotation is also known as the right rotation of the matrix and the anti-clockwise rotation of the matrix is also known as the left rotation of the matrix.
Rotate Matrix 90 Degree Clockwise or Right Rotation
The rotation of a matrix involves two steps:
First, find the transpose of the given matrix.
Swap the elements of the first column with the last column (if the matrix is of 3*3). The second column remains the same.
It is an efficient solution.
If the given matrix is 4*4 matrix, swap the first column with the last column and the second column with the third column.

This is an amazing video of Java Rotate Matrix by 90 Degrees thanks you sir❣❣❣❣❣❣❣❣ i have one questions The interval between two elements in arr is defined as the absolute difference between their indices. More formally, the interval between arr[i] and arr[j] is |i - j|. Return an array intervals of length n where intervals[i] is the sum of intervals between arr[i] and each element in arr with the same value as arr[i]. please
