Coding interview practice, out loud.
Write your code, run it, and explain why it works.
Open the editor
The editor opens on a laptop. Save the link for later.
The editor and code runner are free. Typing with Coco is free when you sign in, up to a daily limit. Talking with her out loud comes with the $79 pack.
def reverse(head):curr = headprev = Nonewhile curr:curr.prev, curr.next = curr.next, curr.prevprev = currcurr = curr.nextreturn prev
after line 5, where does curr.next point?
The learner, out loud: “it flips the arrows and… goes to the next one”
Say it out loud.
In a session with Coco, she listens and asks about your code, one question at a time. She never hands you the fix.
Start with one line.
