Introduction0:26
Intro to the course sections4:58
Master LeetCode in Python by solving mixed-level problems, studying data structures like hash maps and sets, and analyzing time and space complexity to develop problem-solving patterns.

Two Sum16:30
this lecture introduces the two sum problem: given nums and a target, return the indices of two numbers that add to the target, covering brute-force and hash map approaches.
Two Sum Solution10:24
Implement a two-sum solution in Python, starting with a brute-force search and then optimizing with a hash map to find target complement and return the two indices in linear time.
Contains Duplicate7:01
Identify duplicates in an array by pairwise comparison, O(n^2) time; then sort to expose adjacent duplicates, O(n log n) time; and use a set for O(n) time with O(n) space.
Contains Duplicate Solution11:09
Valid Anagram Leet code12:02
Valid Anagram Part 29:26
Use a hash map to count characters in s and t after a length check, use get, compare counts and return true or false; compare with sorting and counter methods.
Assignment Related to Valid Anagrams2:32
This is Assignment where you will able to develop approach towards a particular problem.
Assignment Solution in Python5:01
Improve your Python assignment solutions by using a character counter to detect valid anagrams, tracking counts with a dictionary, achieving linear time and constant space complexity.

Group Anagrams Medium31:49
Top K Frequent Elements16:42
Product of Array Except Self24:31
Master computing the product of array except self in O(n) time without division by using prefix and postfix products, combining left and right contributions in an optimized output array.
Valid Sudoku14:38
Evaluate a 9x9 sudoku board to verify validity by enforcing digits 1-9 per row, column, and 3x3 subgrids, using hash maps to track duplicates.

Requirements

No prior programming experience is required. But It's better if you are have some familiarity with python language

Description

That must be super intimidating to prepare for the interview!"

"Do I need to know them all? How long will I get through all of them?"

You are not alone! We are here practicing the same questions but some question is really important and sometimes fun to know. I list some of them here and let's take a look at them together in course. Join Now.

This course is for all those people who want to learn the data structure and algorithms concepts by pragmatically applying it on leetcode problems and solving it from the absolute beginner to the Intermediate level. We will use many examples to make the lectures very easy to understand and digest.

Each and every problem will have multiple approaches we will try to apply and find the best in terms of complexity i.e principally time and space.

What's Inside :

Leetcode Essentials Problems along with solutions are discussed and Explained . (Essentials)
Different Approaches to the single problem. (Multi-Approach Strategy )
Coding Problems deals with Array and Hashing and Tree (ad and Graphs and Further more will added as you keep going..
Understanding Patterns and Competitive based approaches.

What is LeetCode?

LeetCode is a huge repository of real interview questions asked by the most popular tech industries (Google, Amazon, Facebook, Microsoft, Apple, Quora, LinkedIn, Bloomberg, Uber, Goldman Sachs, Twitter and more ).

Interviewers from the most popular companies(like Google, Amazon, Facebook, Uber, Twitter etc.) often directly ask questions they find on LeetCode. It's hard to navigate through the large amount of problems(around 1500) to most important questions, this is what this course stand for.

I am currently spending substantially hours on LeetCode and trying my best to provide and deliver this concepts to you . From my experience, I'm telling you that you don't have to do the all the problems just you need to do the problems which will built your concepts and others problems are either subset or super set of that generally. These types of algos based problems will you be able to see here. I will try to keep this course updated as possible so that can add more sections in it as per IT demands.

By the time you're finished with the course, you will be prepared for common technical coding interview questions.

See you inside the course!

Who this course is for:

Software Developer or Intern who are are curious about problem solving in python
