iPad PDF NOTES - https://github.com/MAZHARMIK/Intervie... Whatsapp Community Link : https://www.whatsapp.com/channel/0029... This is the 31st Video of our Playlist "DP Concepts & Qns" by codestorywithMIK We already covered the introduction of DP On Grids in video-29 and video-30 of this playlist. Video-29 - Part-1 -    • Introduction | DP On Grids | Part 1 | DP C...   Video-30 - Part-2 -    • Introduction | DP On Grids | Part 2 | DP C...   Now, we will start solving Questions based on DP On Grids. Today we will be solving a Medium and popular problem based on Grid DP - Unique Paths | Recursion | Memo | Bottom Up | Leetcode 62 | DP On Grids | codestorywithMIK We will solve it using Recursion and Memoization and then we will convert that to Bottom Up. I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY. We will do live coding after explanation and see if we are able to pass all the test cases. Also, please note that my Github solution link below contains both C++ as well as JAVA code.

Memoization (a 2D array t) is used to store intermediate results to avoid redundant computations. Base cases handle out-of-bound conditions and the finish cell. Recursive calls sum up the ways from the cell below and the cell to the right. Approach 2: Bottom-Up Dynamic Programming This approach builds a 2D DP table iteratively, where t[i][j] represents the number of ways to reach the cell [i][j]. The values are calculated based on the sum of ways from the cell above [i−1][j] and the cell to the left [i][j−1]. First row and column are initialized to 1, as there is only one way to move along these edges. The value at [m−1][n−1] represents the total unique paths. ✨ Timelines✨ 00:00 - Introduction 0:10 - Motivation 1:15 - Problem Explanation 3:29 - Thought Process Recursion & Memoization + Decision Tree 12:56 - Time Complexity 16:23 - Coding Recursion & Memoization 19:25 - Understanding Bottom Up 34:31 - Coding bottom up #MIK #mik #Mik #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge #leetcodequestions #leetcodechallenge #hindi #india #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge #leetcodequestions #leetcodechallenge #hindi #india #hindiexplanation #hindiexplained #easyexplaination #interview#interviewtips #interviewpreparation #interview_ds_algo #hinglish #github #design #data #google #video #instagram #facebook #leetcode #computerscience #leetcodesolutions #leetcodequestionandanswers #code #learning #dsalgo #dsa #coding #programming #100daysofcode #developers #techjobs #datastructures #algorithms #webdevelopment #softwareengineering #computerscience #pythoncoding #codinglife #coderlife #javascript #datascience #leetcode #leetcodesolutions #leetcodedailychallenge #codinginterview #interviewprep #technicalinterview #interviewtips #interviewquestions #codingchallenges #interviewready #dsa #hindi #india #hindicoding #hindiprogramming #hindiexplanation #hindidevelopers #hinditech #hindilearning #helpajobseeker #jobseekers #jobsearchtips #careergoals #careerdevelopment #jobhunt #jobinterview #github #learningtogether #growthmindset #digitalcontent #techcontent #socialmediagrowth #contentcreation #instagramreels #videomarketing #codestorywithmik #codestorywithmick #codestorywitmik #codestorywthmik #codstorywithmik #codestorywihmik #codestorywithmiik #codeistorywithmik #codestorywithmk #codestorymik #codestorwithmik
