Welcome to the Course,
This is the introduction lecture only, We will be starting with problems, seeing all different approaches to problems, and will then implement a solution.
It's simply as simple as that. We would also be covering some of the related DSA concepts going further.
Explores a 2sum brute force solution in Python, analyzes its O(n^2) time complexity, and notes its inefficiency and potential optimization using ad edge.
Explore the 2sum efficient approach using hashmaps to check the needed element and identify pairs, while considering solution complexity.
Learn to implement the 2sum solution in Python using a hashmap to store numbers with their indices, check the complement of each number, and return the valid pair.
Master the two-sum problem for a sorted array using a two-pointer approach, moving low and high indices and adjusting based on the target to find pairs.
Learn to solve balanced parentheses in Python by implementing a stack data structure, a practical technique for interview starters.
Count zeros, ones, and twos in a single pass and rebuild the list using those counts, then consider a new array versus in-place overwrite under space constraints and time complexity.
Learn to remove adjacent duplicates in a string by using a stack-based approach, exploring different strategies and analyzing time complexity to build efficient solutions in Python.
Learn to remove all adjacent duplicates in a string using a Python list as a stack, implementing push and pop operations to produce the final result.
Master the logic to identify the second highest value in an array and apply critical thinking to compare data points for clearer decision making.
We will see some frequently asked questions from Actual Interviews, and build solutions on them in a Systematic way.
We will cover questions based on the simplest approach first, then try to think of more optimal solutions as the Course Progresses,
The Central Idea is to practice different ways on a single problem and think of better solutions, Keep up with me, We will together get the things done and it would be fun to learn.
I would be using Python 3 as the Programming Language, However, you are free to use any language you want because the concept remains the same, For python users, I would be using PyCharm, You can Install Pycharm for the same.
We would be discussing several coding techniques
Anyone with a basic background in programming can take this course, Even if you are a complete Beginner.
I would suggest you keep practicing as this is the only way to understand things better, you can use any coding platform, just keep the consistency and commitment, and you will rock, that I guarantee.
I have collected questions from actual interviews and also from LeetCode and similar coding platforms, You will have a single place for all of the questions to practice and discuss.
