Leetcode Solution | Getting Started and 1.0. Two Sum | Javascript | 1/75

[@meilyn22]

Boy, I've never seen someone solve a problem that I understand so well. For the first time I could actually predict what code should come next. You are the best. Don't stop. You will blow up soon because you are a great teacher. I have seen many tutorials on solving leetcode, but it's just the do what I do type of solution without walking through their thought process. I could actually understand why you did everything in your code. The pseudocode helped do wonders. I am a beginner, I thought double for loop was for a multidimentional array, but you just taught me sometime brand new. thanks man.

I'm so happy I found this video as I begin my Leetcode studying! The tier breakdown will definitely help organize the practice problems. Thank you!

Great job brother Much appreciated!

Good work man. 👍

if you sort the array and look with two pointers, the found indices would be the sorted array's indices. After that we need to find the original indices as well. Isn't that make it very slow?

[@georgietrottier9312]

Hey , that's an awesome explanation! Though, I wanted to ask why we need to sort the array to solve this question with two pointers? Can't we do it without sorting? If no, then why?

[@ThinkFWD]

Sorting gives you a natural attribute of higher value on right and lower value on left. Knowing this allows you to make a decision once you take 2 elements and add it together and minus target. You will know if you need to move up from left or right based on the outcome. :).

Can we do it with two pointers

[@ThinkFWD]

Yes you can ;) I wanted to leave that for you to try at the ends
