Wouldn't the nested while loop make this an O(n^2) time complexity?

[@bessamlegrand]

Yes i was about to say the same thing

[@TylerKaihara]

No, because you are only visiting each node once

I wanted to say algo 2 times

Can anyone please help me understand why changing the value of prev results in changing the value of dummy as well? Is it because of the line 15 where it has: let prev = dummy Why can't you use dummy in the while loop? I got the logic, but I can't get my head around with how the ListNode works...

[@mansoorqaisrani5644]

the value of dummy is not changing. It is dummy.next which is changing.
