Let’s consider a square matrix of n x n. (n columns and n rows). The diagonal difference of a square matrix is the absolute difference between the sums of its diagonal.
Let’s look at an example based on the following 3 x 3 square matrix:
Here is how we would calculate the diagonal difference for this matrix:
Python Challenge
We have created a Python script that asks the user to input the dimension n of a square matrix (any positive integer value). Our python scripts generates a n x n matrix using random values and displays it on screen as a 2D grid.
Your task is to complete this script to automatically calculate the diagonal difference of the given matrix. (Make sure this value is always a positive value!)
Python Code
Extension Task #1
Your first extension task is to create an additional function to calculate the sum of the 4 corner values of the square matrix:
Extension Task #2
Your second extension task is create an additional function to calculate the average value of all values stored in the matrix.
