This is the only explanation that makes sense, I prefer this over the neetcode video.

a issue which might be either me or bcom someone elses problem
in ur c++ solution : correc the dummy node initialization ListNode*dummy = new ListNode(0), this works everytime and doesnt produces error

thanks greg, i was not able to understand how its O(1) space until i saw your whiteboarding

AmanjotSingh-rjox

loved the explanation
i've watched other videos where they created a new list and just added the values in sorted order
changing the pointers is what was asked here
Thank you very much <3

What would a solution look like if we were asked to create a new node and then add it to our linked list? I am trying to implement that but i am struggling

Thank you for the explanation. Very clear and neat. I'm a python-virgin and have two trivial questions
1. how do you test the code? I've written a code and test it on leetcode and it's fine but when running on python, I can't test it and got error!
2. Why do you insert # behind ListNode class? if it is excluded from the code how does the remaining part of the code work?
