No, it's like this:

Expected <------ THIS IS YOUR WRONG ANSWER, NOT THE INPUT
    <[]int | len:20, cap:20>: [5, 6, 8, 1, 7, 3, 1, 9, 0, 1, 0, 0, 0, 0, 9, 0, 0, 0, 0, 0]

to equal <------- THIS IS THE RIGHT ANSWER
    <[]int | len:20, cap:20>: [5, 6, 7, 8, 1, 1, 3, 1, 9, 9, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

To see the input, print it: https://docs.codewars.com/training/troubleshooting#print-input
