Hi Salah, I’m sorry that it seemed too difficult! I intentionally wanted to choose a question that most people would consider “hard” to show you that if you follow these steps, you can solve any question, even if it’s very difficult. May I ask which parts you couldn’t understand? Maybe I can provide clarity and make my future videos better.

A hash map is a common data structure across all languages. Java has its own specific implementation of hash maps called HashMap.

@@Codebagel in JavaScript a hashmap is exactly an object key value pair

Good catch… 😅 after hours and hours of editing you’d think I’d catch everything but sometimes something slips through. Thanks for catching that!

Hahah I'm sorry, didn't mean to devalue the effort at all. This video was incredible and thank you very much for making it 🎉❤

@@yohahnribeiro6029 Haha no worries not at all! I actually like it when people point things out because I know to keep an eye on that for future videos! Only way to grow is to learn from mistakes, so thank you 😁

Thank you so much! I appreciate that you’ve been here since the start, hopefully I can keep making content that you can enjoy!

hey, i want to ask you wether you did all of the questions on leetcode by you own without any help or you tried and when you were not able to solve it than you referred to any yt video? i am doing leetcode so i am not able to solve the questions ... i try to solve one question for 1 hr or more and than i refer to yt video. is this good ? any suggestions? Thanks

@@vrajpatel9259 Sure. Since you and my past self have no idea how to play the Leetcode game. Once you have no idea how to do it or don't understand the question within 10 mins , just look for the answer. There is no shame to look at it. The way I still doing it is look at the approach , and use that approach to create your own code.

​​@@vrajpatel9259hey we are on the same page. But you know that's the way of getting learn from mistakes. Keep it on mind where we struck, why does it happens every time? Try 30-40 mins max for any level of question even though can't trick the solution then try to approach other's intuition and code, then try a dry run on your own.. That's where I found my solution. Keep it up buddy... Have a nice day

Haha thank you! Hopefully it won’t be for long 🫣

Hanji mere paas job hain (hopefully that makes sense, still learning the language)

Thanks so much! Glad you like it!

I agree! Every backend engineer should know SQL and database work!

Hi! What areas do you find you struggle with the most? Is it recognizing the pattern? Is it knowing what to code?

@@Codebagel both. Sometimes know the approach but not able to convert it into code.

I'm facing the same problem

Solve recursion problems

Sir please can you educate me more based on your experience, i started with C++

@@rex_richies if you know C and C++ it means you know the working of pointers ,stack ,heap . Now choose any domain like web dev , mobile app dev , blockchain dev or embedded system in which you are interested . Java and javascript is the most used language in the market so it will be better to learn any of it and its framework if you want job asap

The more you are good at solving these problems, the more you are able to come up with solutions for real-world probelms.The probelms test your ability to understand the requirements and write corresponding code for the same. So that's only way to test logical and analytical capabilities of a programmer.

The flow chart is amazing 👌

I’m glad it helped!

Great idea! Algorithms make up so much of coding, it’s super important to know the fundamentals.

Thank you!

Thanks so much! Walking through problems with a flowchart is a really systematic way to approach problems, and something I think engineering-minded people really benefit from.
