Join this channel to get access to perks and support my channel:

In this video, I continue solving the Neetcode 150 problems, tackling questions 52 to 95. This is Part 2 of a comprehensive 3-part series aimed at covering all 150 Leetcode coding questions. These problems are among the most important data structures and algorithms questions you’ll encounter in technical coding interviews, making it an essential resource for those preparing for FAANG interviews and software engineering interviews.

This video includes step-by-step solutions and in-depth explanations for a wide range of topics, from binary trees and dynamic programming interview questions to graph problems and backtracking. Whether you're a beginner or an experienced coder revising algorithms important questions, this series will help you strengthen your problem-solving skills and get ready for your next interview.

I’ve designed this video to be an all-in-one guide for mastering common programming interview questions, including dynamic programming revision, data structures questions, and interview example questions and answers. My goal is to provide you with the confidence and knowledge to succeed in FAANG DSA interview questions and advance your software engineering career.

Hi Parth, just come across your videos and I am really loving it. First thing first please dont stop it. Even though your views are not much but the quality is way better than the guys whos views go in million and trust me you will get those views soon.

Here is me: I switched to development few months ago from a process mining field even though I have degree in cs but i was not in touch with code since last 7 years but this year i stepped in but I struggling in every aspect of development whether it is problem solving, logic, coding, other stuff but my end goal is to get into FAANG.

Why i shared the history is to just ask this question .

Now a days in india you know lots of layoffs are going and to be really frank I am considering myself as well in layoff because I know I am poorly performing but I dont have issue in it I wanted to prepare and give interview in development so will company entertain me for lets say 1-2 years development role as I am having 5.7yrs of IT experience out of which 5.2 is of process mining?
