Could you make a video on implementation of hash table as well as it was asked in Sprinklr interview in intern in our college.
This DSA playlist will be appreciated for hundreds of years.❤

I feel like within 20 years from now striver will make another series that works on quantum computers and that will live for 100 years.
If i had teacher like him in my college I wouldn't have watched KZread channel before day of exam... The way he teach and make us understand concept...hatsoff sir Also thank u for free DSA course🙏🙏

Oh My God!!!!!!!!! Even after knowing Hashing came here...because I was very sure...Striver's video will definitely have something valuable. You are truly a Gem Striver. Always grateful to you🙇♀
In glaobl and main(), max size decleration concept in array is very helpful and In another conceptual question also. Your best thing in every tutorial i liked so much is you taught us question from BFS approach to Optimised approach and by different method you solved question and also taught us the preferable method accoding to it's space and time complexity. Topic covered:- -> For loop method (BFS) -> Array hashing (Optimised) -> Number hashing -> Character hashing (2 method) -> Maximum size concept in decleration of array size. -> TC difference by using in map and unordered_map STL (normally Unordered_map way is prefered by you) -> Method of Hashing -> Explain Division method - linear chaining concept -> Collision (that's why why worst case TC is O(n) by using unordered_map STL) -> Key-Pair data structure and data type decleration difference in map & in unordered_map Thankyou Striver for such an amazing content. 🔥🔥
