Tell us what’s happening:

I seem to have the correct line of code but it isnt passing the test.

Your code so far

NUMBER_OF_DISKS = 4
rods = {
    'A': list(range(NUMBER_OF_DISKS, 0, -1)),
    'B': [],
    'C': []
}


/* User Editable Region */

def move(n, source, auxiliary, target):
    if n > 0:
        # move n - 1 disks from source to auxiliary, so they are out of the way
        move(n - 1, source, auxiliary, target)
        
        # display starting configuration
        rods[target].append(rods[source].pop())
        print(rods, '\n')

              

/* User Editable Region */

# initiate call from source A to target C with auxiliary B
move(NUMBER_OF_DISKS, 'A', 'B', 'C')

Hello oluf,

The logic is correct, but it’s not part of displaying the starting configuration. It wants you to write it above the last comment.
