Is this a common practice in USA? Never seen that in Europe for software engineers. What of you couldn't solve it?

There is *indeed* a bug in this solution. Consider the scenario where the given binary search tree did not contain the node with value 25, and the input node was the node with value 20 (the root node). In this case, the program would crash on line 48 due to dereferencing a null pointer. Namely, parent is null, so parent.right will crash. The solution is to replace the code from lines 48 through 56 with the following code: while (parent != null && parent.right == child) { child = parent; parent = parent.parent; } return parent; Note, the only changes are (1) the condition of the while loop, and (2) the removal of the if condition.

after studying and learning to code for 3 years. I never had 1 white board problem at an interview

When the interviewer challenges an interviewee with a question that has been challenging for himself for a while!! not a good idea!!

in your life. you never going to use it. and this is kid game

可惜。這個例子舉得不好。

one year waiting period.... oh thats a gross

really good explanation, saved a lot of time!

This Video was indeed very helpful. I finally understood all the principles!!

Space complexity is 0(1) dear lord yall.

parent class/ children class; super class/ sub class;

I know the STAR method says to state the Situation first, but I feel like you could put ahead off of it the summary: "I moved everyone to vue.js", or "I broke an app." Helps to follow the story

I have been part of AWS interview and not Google's. Let me tell you, AWS will still definitely beat Google in being the most stupidest process, horrendous, mind boggling, and to simply sum up - Didn't make any sense at all for me.

Although it's impossible - I can see the goal of tech questions trying to gauge where you are in your coding skills. If there are 25 core concepts to coding, then perhaps try to ask a tech question (or even better - questionS) that touches all these concepts

fakeo

Great tuts !

The job market is super tough right now in 2024-2025 people now a days are not asking these kinds of question anymore 🥹🥲

Yup, coding is not for me.

This type of interview can provide insight into how a candidate thinks about and solves problems. However, in real life, it's unlikely that you'll write something like this, as most of our work involves implementing commercial products with maximum efficiency. Additionally, with advancements in AI pushing the boundaries further, the interview should also assess soft skills. I wouldn't hire someone who is excellent at algorithmic coding but incapable of creating practical solutions for my company.

Fake video interview btw.

Lmao my director told me exactly why as a high level coder he doesn’t do this shit to people he interviews.. it’s pointless and says nothing about the quality of work the candidate is capable of.

props to you brother, you gave it your best!

This was an amazing recap, thank you very much

Nowadays, in 99% of the jobs, the most useless coding interview you will never see

thank you!

gonna learn Java

I can solve this question in best time complexity through single while loop iteration

If you can, try to use a complicated/challenging story (make sure that you're able to explain it in a clear and concise way) this will impress the interviewer. For big companies simple stories might not work. The bar is quite high! I would recommend be prepared with 5 complex and 5 simple stories. Cheers!!!

Great video.

teacher, may I know why u name your 1st java file name as "main.java" not "classname"?

Thank you I'm coding even I'm a kid just need to understand. Thanks I'm starting tomorrow 😅😅😊

He didn’t put one of the best ones (brilliant)

well explained

Scratch

Thank you, I was thinking about these questions totally wrong until watching this video. I was thinking of code, tech, minute details, features. But u made me realize there's a lot more to talk about.

Was it must to name your first file "main.java"?

I might be wrong, but isnt just a simple inorder traversal can make it work.

Great short!

i guess : public and static have something to do with OOP's features such abstract and polymorphism. Am i right?

honestly, when it comes to ease, learning with the big 3: html, css javascript was how I started out.

btw "void" also

@Dear teacher: u forgot to address what "static" and "public " are for ?

Thanks so so informative

I got confused who is the interviewer and who is the interviewee 😂

You just need a recursive function to "parcours" the tree and add the greater nodes to an array, then select the smallest node from the array... "et voila!"

Bro is spending his whole savings to code that Bubble Sort.

Damn after i burn my brain i understand some of stream concepts

This is a nonsense question! You almost never encounter such problems in real-life development unless you're working on something as specific as building a new programming language. Most programming environments already provide abstractions for these kinds of issues! It’s unreasonable to eliminate a developer just because they didn’t pass this test.

From my experience working with AOSP and developing drivers for Android, I don't forsee Google stopping support for Java there is a hell lot of java nightmare inside the android OS, Moving them to a new language will result in developer hell.

I don't think coding interviews are this easy.
