Day 44 of #SDESheetChallenge - Binary Tree to Doubly Linked List Find Median in a Stream K-th Largest Element in a Stream Focused on - Tree Transformations, Heaps & Efficient Data Stream Handling @takeUforward_ @striver_79 #DSA #SDESheetChallenge #BST

Day 5 of GenAI with JS- Started building a ChatGPT streaming clone. Today's session covered Next.js setup, Shadcn UI integration, database setup, schema creation, Clerk authentication, and CRUD operations for conversations @ChaiCodeHQ @surajtwt_

Day 43 of #SDESheetChallenge Two Sum in BST BST Iterator Largest BST in Binary Tree Serialize & Deserialize Binary Tree Focused on - BST Traversal, Tree Properties & Serialization Techniques @takeUforward_ @striver_79 #DSA #BinarySearchTree #ProblemSolving #SDESheetChallenge

Day 42 of #SDESheetChallenge - Floor & Ceil in BST K-th Smallest Element Kth Smallest & Largest in BST Focused on - BST Traversal, Ordering & Optimization @takeUforward_ @striver_79 #DSA #Java #LearningInPublic #BinarySearchTree #Algorithms #ProblemSolving #SDESheetChallenge

Day 41 of #SDESheetChallenge - Construct BST from Preorder Validate BST LCA in BST Inorder Successor & Predecessor Focused on - BST Properties, Recursion & Efficient Searching @takeUforward_ @striver_79 #DSA #BinaryTree #Recursion #Algorithms #ProblemSolving #SDESheetChallenge

Day 40 of #SDESheetChallenge - Populating Next Right Pointers Search in BST Construct BST from Given Keys Focused on - BST Operations, Tree Connections & Recursion @takeUforward_ @striver_79 #DSA #Java #BinaryTree #BST #Recursion #Algorithms #ProblemSolving #SDESheetChallenge

Day 39 of #SDESheetChallenge - Symmetric Binary Tree Flatten Binary Tree to Linked List Check Symmetrical BTs Children Sum Property Focused on - Tree Recursion, Traversal & Tree Transformation @takeUforward_ @striver_79 #DSA #TreeTraversal #DFS #Recursion #Algorithms

Day 4 of GenAI with JS- Biggest realisation: LLMs aren't real-time—they only know trained data unless we provide fresh context. Explored RAG, its indexing & query pipelines,& how it solves context window/token limitations. Excited to build with these concepts @ChaiCodeHQ

Day 38 of #SDESheetChallenge - Maximum Path Sum in Binary Tree Construct BT from Preorder & Inorder Construct BT from Postorder & Inorder Focused on - Tree Recursion, Traversal Logic & Divide & Conquer @takeUforward_ @striver_79 #DSA #BinaryTree #TreeTraversal #Recursion #DFS

@nirudhuuu Thank You Very Much Sir ✨🙏

@_kumar_pratham Congratulations

6 months ago, I started with curiosity. Today, I'm proud to have completed the Full Stack Web Development Cohort by @ChaiCodeHQ. Built real-world projects, learned every day, and grew as a developer. The cohort ends, but the journey is just beginning. Thank you, @ChaiCodeHQ🙏..

@MalhotraSa6586 @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme @ChaiCodeHQ @devwithjay @BlazeisCoding @Aasuyadavv Congratulations 🎉🎊✨

Officially completed the ChaiCode Web Dev Cohort 2026! ☕ 6 months of learning, building, debugging, and growing as a developer. Grateful for every lesson along the way. Huge thanks to @Hiteshdotcom, @piyushgarg_dev, @nirudhuuu, @yntpdotme, @ChaiCodeHQ for the amazing mentorship.

@Yasshiika @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme @VinnyMadaan3 @Shivam_Goyal_20 @BlazeisCoding @surajtwt_ Congratulations 🎉🎊

Started this cohort hoping to become a better developer. Graduating today with countless lessons, projects, and memories. ❤️🎓 Never imagined I'd learn so much and build beyond my expectations. Thank you @Hiteshdotcom, @piyushgarg_dev & the entire ChaiCode team! 🚀

@the_vraj_soni @xp_vishal @ChaiCodeHQ @Hiteshdotcom @BlazeisCoding @devwithjay @surajtwt_ @nirudhuuu @piyushgarg_dev @yntpdotme Sure

@_kumar_pratham @xp_vishal @ChaiCodeHQ @Hiteshdotcom @BlazeisCoding @devwithjay @surajtwt_ @nirudhuuu @piyushgarg_dev @yntpdotme Lets connect

So..that's a wrap for the Web Dev Cohort @ChaiCodeHQ💓 We started as learners. We leave as builders. 6 months of consistency, debugging, shipping projects, & growing together The classes are over, but the journey has just begun See you all on the internet, building amazing things

@codeXninjaDev @ChaiCodeHQ @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme @BlazeisCoding @devwithjay @surajtwt_ Congratulations 🎉🎊✨

They finally gave me a certificate instead of another assignment. 😭❤️ Passed the graduation exam & officially graduated from the ChaiCode Web Dev Cohort 2026. Guess I'm allowed to write Full Stack Developer without feeling guilty now. 👀
