hearing "hey guys i'm still unemployed so let's solve a leetcode problem today" and knowing you became a software engineer at google is so real and inspiring bro, thanks

[rohitkumarsinha]

"hey guys i am still unemployed so lets solve a problem " this is savage bro

[chair_smesh]

I get so inspired/motivated when you mention unemployment in your old videos because of where you ended up

[bigrat]

"hey guys i am still unemployed so lets solve a problem " this one cracked me up because right now all your efforts paid off and look back, we all have been there..ah what a journey!!!

[mehmetnadi]

I've been watching your solutions for a while now and I'm just so happy that I finally started to solve problems like the way you do. Thank you so much!!

[snoudoubts]

That beginning took me by surprise, instantly made my evening better. Thanks

[Eftahhh]

So simple, thank you. I was casting the linked list values to strings and reversing them, then casting them back to ints and adding them... needless to say I was making spaghetti.
Your example is very clean!

[syafzal]

Awesome, I love how you dealt with all the edge cases without cluttering the code

[philhamlin]

Excellent! Clear and plain explanations, and it's so much cleaner when hand mark-up is by pen instead of by mouse. :)

This is linked in LeetCode as "optimized solution explained" on the problem itself, but it'd be faster to take:
carry = val // 10
val = val % 10

...and make it instead:
carry = 1
val = val - 10

The modulus approach is fantastic for expanding our algorithm to support adding up three or more arrays, but in our use case carry will always be 0 or 1.

Congratulations that you are now employed!! Happy for you!

I traversed through both linked list and got the actual numbers, added them, then created a linked list with the result's digits as nodes.

[anthonypeters]

Couldn’t have solved this without you. Thank you so much

[passionatechristianworker]

i'm amazed at your ability. it's the nuances in the code that's the hardest to figure out. kudos to you.

[MrYosuko]

The intro slapped me back into reality. As always, thanks for the awesome explanations 😄

[passionatechristianworker]

"you probably do but you might think you don't".

Haha, thanks for the encouragement.

"hey guys i am still unemployed so lets solve a problem" mans representing his entire audience 😂😂😂

[SweVillian-mtnk]

This intro make this video my favorite one 😂. Could be a useful cue to remember the solution in an interview even.

[raymondcordero]

By far the best explanation of this problem I’ve seen 👏 Thanks for sharing

[ishaanbhalla]

Man I was super stressed out solving these leetcodes, but the " Hey I am still unemployed" made my day! LMAO

[techbrojoe]

Thanks for making this. Trying this problem is the first time I've ever tried using a Linked List, so this helped solidify the solution LeetCode provides.
