| # Create a array with numbers from 1 to 100 in a random order | |
| ary = (1..100).to_a.shuffle + (1..100).to_a.shuffle | |
| idx = 0 | |
| paired = ary.map.with_index { |value| [value, idx += 1] } | |
| # Now the numbers are paired; the first is the random number 1-100 the second is its sequence within the 200 entries | |
| puts paired.inspect | |
| # You'll see many entries with equal first values where the first of them has a higher second (sequence) number, meaning it's out of order now |
