Shuffling a 2D Array

For this challenge we will investigate how to create a 2D array to store the value from 1 to 100 in a 10×10 array. We will then write an algorithm to shuffle the content of this array.

See the code below to see how the array can be initialised to contain all numbers from 1 to 100 and how it is then displayed on screen.

Your Challenge

The aim of this challenge will is add a function to the code above to shuffle all 100 values inside the array:

Solution

Check the following flowchart for a solution that:

• Accesses each value of the array one by one (using two nested loops),
• Swaps each value: it swaps the value with another value of the array at a random position.
