When you’re stuck on a problem, here are places to look for help:

NeetcodeA YouTube channel and website with excellent explanations for hundreds of Leetcode questions. These videos walk through multiple strategies for each problem and include visual explanations and full code to solve the problem.

LeetCode solutions/other online answersThe “Solutions” tab on LeetCode lets you find solutions and is organized by language and algorithm. If there aren’t great solutions for a certain problem, you can Google the problem’s title, and often you’ll be able to find fully-explained answers on Stack Overflow or other forums.

Friends/classmatesWorking on/debugging programming problems with others can be extremely beneficial. Other people may see errors in your code that you don’t, and explaining your thinking is a great way to consolidate learning.

LLMsChatGPT and other LLMs can explain a problem to you when you paste in a link to the LeetCode question. As always, AI can be wrong, but typically it knows what it’s talking about.
