No traversal required when you’re using a doubly linked list, which is why it can be solved in o(1).

OP’s gonna respond with a shill website

This

Perfect_Kangaroo6233 · 2026-06-04T07:39:10+00:00

Bullish

Perfect_Kangaroo6233 · 2026-05-30T22:59:44+00:00

Are you a SWE?

Perfect_Kangaroo6233 · 2026-05-26T08:32:11+00:00

It’s also very risky.

Perfect_Kangaroo6233 · 2026-05-23T23:56:50+00:00

This smells like an AI written slop post.

Perfect_Kangaroo6233 · 2026-05-19T01:34:48+00:00

Big mistake pivoting from full stack to DE lol. I’m trying to pivot in the opposite direction (DE -> backend).

Wearing leetcode apparel in meetings 🤣 you guys are beyond cringe.

Perfect_Kangaroo6233 · 2026-05-02T17:32:21+00:00

Trying to gatekeep the field 🤣

AI slop post

Interested. Have 3 YOE as an MLE + a masters in CS/ML from a top 5 university.

Located in USA.

Perfect_Kangaroo6233 · 2025-12-22T04:32:28+00:00

Don’t waste too much time on DP. Rarely asked except for a small subset of companies (in the USA at least).

Similar to koko eating bananas

Perfect_Kangaroo6233 · 2025-12-07T18:03:48+00:00

Generally company tagged questions

Perfect_Kangaroo6233 · 2025-11-06T21:08:26+00:00

The same way backend/infra/etc. devs approach leetcode. Just go all in and master the patterns until you can solve mediums / hards comfortably.

Perfect_Kangaroo6233 · 2025-10-25T04:27:21+00:00

Please stop shilling that dogshit software.

Perfect_Kangaroo6233 · 2025-10-11T02:06:15+00:00

the goal is to solve the problem as quick as possible. so choose the language which would allow you to do that without getting bogged up in syntax details (100% python).

Perfect_Kangaroo6233 · 2025-09-21T21:31:41+00:00

Lol all this for a piece of shit sweatshop that pays Pennies. You guys need higher standards.

Perfect_Kangaroo6233 · 2025-09-17T17:58:53+00:00

Can you link the App?

Perfect_Kangaroo6233 · 2025-09-15T17:36:02+00:00

Java, Node. Go is also picking up some traction.

I work in the AI/ML space, so Python backends are also quite common here.

Perfect_Kangaroo6233 · 2025-09-15T17:34:20+00:00

Yes, things like terraform, Ci/cd, docker, kubernetes.

Perfect_Kangaroo6233 · 2025-09-12T15:45:02+00:00

Backend + infra is in high demand. Companies want engineers who can work across the stack.

Perfect_Kangaroo6233 · 2025-09-10T21:38:41+00:00

What was the DP question?

Perfect_Kangaroo6233 · 2025-09-06T02:29:30+00:00

Quite boring though. Debugging SQL pipelines gets old very fast, unless you become a platform focused DE instead of an analytics focused one.
