Randomizing array elements

Question

I have an array @number = [1,2,3,4,5,6,7,8,9]
Now, I want to randomize the array content... something like eg: [5,3,2,6,7,1,8]
Please guide me how to proceed with it.

Answer 1

Use the shuffle method ...

irb(main):001:0> [1,2,3,4,5].shuffle
=> [3, 4, 2, 5, 1]

Answer 2

the shuffle command returns a randomized version of an array

eg:

[1,2,3].shuffle => [2,3,1]
