Interview Summary

Problem type
Sort colors
Interview question

  1. Given an array nums with n objects colored red, white, or blue, sort them in-place so that objects of the same color are adjacent, with the colors in the order red, white, and blue. We will use the integers 0, 1, and 2 to represent the color red, white, and blue, respectively.

  2. Given an array of Tree nodes, return the root node.

Interview Transcript

The Masked Hedgehog: Hey, good afternoon.
Hot Gyro: Good afternoon. How are you?
The Masked Hedgehog: I'm good. Thank you. How's it going?
Hot Gyro: It's going well, it's pretty sunny today, for me. So we have an hour together for a coding session. Is that correct?
The Masked Hedgehog: That is correct. Yes.
Hot Gyro: I have a couple of questions prepared. But I'd like to ask you, do you prefer a harder problem or an easier problem?
The Masked Hedgehog: I think, let's go with an easier problem.
Hot Gyro: Okay, sounds good...

(Tanscript continues with the conversation regarding problem-solving strategies, feedback on coding skills, and further discussions about different coding approaches.)

Coding Problem Overview

Input: An array of integers (0, 1, 2).
Objective: Sort the array in-place.

The interviewee discusses various sorting algorithms and the interviewer provides guidance on improving the approach.
