102. BT Level Order Traversal. this question is a medium question where we have to add the currLevel node into answerList and return the ans. the main issue with this problem was how to get the level and add them into the list to counter that we will be using queue. #JoongDunk

104. Maximum Depth of Binary Tree this approach basically add the initial element in the que and then push it's left and right child until it found null and after completing the loop,we are increamenting the size with one. #program #Trending #artificial_intelligence #java #Coding

problem no - 106. Construct Binary Tree from Inorder and Postorder Traversal, this question was so confusing as we have to take care of the root initially and then solve the subarray accordingly with inorder and postorder. #Java #ArtificialIntelligence #interview #Trending #FAANG

here's kinda medium problem, 98. Validate Binary Search Tree the main issue with the problem is you have to take care of the min and max, and even after that i was able to pass 76/89 test cases because of the data type. #program #Trending #ChatGPT #Grok #Coders #interview #Java

Hello coders, 94. Binary Tree Inorder Traversal, the problem statement simply want us to apply the inorder traversal on the binary tree. Inorder traversal in nothing but traverse leftST>process root> traverse rightST #Coding #artificalintelligence #Coders #Trending #instagram

Good Eve Everyone, 1094. Car Pooling, this problem is kinda tricky in which you have to take care of the passenger who are sitting in the car while thinking of that the passenger should not exceed the capacity. Hint:- PrefixSum Array. #CODE #Interviews #LeetCode #Trending #Coding

Hello guys, Another day of learning, 450. Delete Node in a BST, this was a very interesting question as in this question we have to take care of the multiple cases and run again and again the stack calls to see if everything is going well planned. #javaDeveloper #DSA #java #AI

Hello guys :) Today,I solved LeetCode 987 – Vertical Order Traversal of a Binary Tree. While solving, I realized I needed to traverse nodes according to the y-axis. To handle this, I created a Map<y -> x-> List<Integer>> used TreeMap maintain order. #Java #DSA #ProblemSolving
