@yerique_ That makes sense! I will focus on consistency and gradually increase my DSA time. Thanks for the advice! 🙌

Day 9/21 — DSA
Today’s problem: Ceil in a BST.
A simple question taught me something important:
Don't always search everything. Use the structure you’re given.
My solution is basic, but I'm learning to recognize these patterns.
What DSA pattern are you learning?

Day 8/21 🚀

No new LeetCode problem today.

Today was about revising what I’ve learned so far and connecting with more people in tech.

Revising → Understanding → Building → Connecting.

Looking to connect with developers, engineers, students & fellow builders.

Day 7/21 — DSA 🌳
Solved: Search in a Binary Search Tree. New learning: BST property makes searching simple:
→ key < root → go left
→ key > root → go right
→ Equal → found.
Instead of checking every node, each comparison eliminates half the search space.

Day 6/21 — DSA
Solved: Construct Binary Tree from Inorder & Postorder Traversal.
New learning:
→ Postorder gives the root from the end
→ HashMap gives the root's position in Inorder
→ Inorder splits left & right subtrees
→ Recursion builds the tree

[Yash Gupta @yashyrsgupta]

Day 5/21 — DSA 🌳
Solved: Construct Binary Tree from Preorder & Inorder Traversal.
New learning:
→ HashMap stores Inorder positions
→ Preorder gives the root
→ Inorder splits left & right subtrees
→ Recursion builds the treePreorder + Inorder → Binary Tree 🚀

[Yash Gupta @yashyrsgupta]

Day 4/21 🚀
No LeetCode today.
Instead, I spent some time thinking about what I actually want to become as a developer.

Still learning & building:
→ DSA with Java
→ Full-stack

Still learning, still figuring things out.
If you're also learning/building in tech, let's connect.

Day 3/21 — DSA
🌳Solved: Count Complete Tree Nodes
Key points:
→ If left & right heights are equal, the tree is perfect
→ Nodes = 2^h - 1
→ Otherwise, recursively count nodes. Tree properties can turn brute force into an optimized solution.

[Yash Gupta @yashyrsgupta]

Day 2/21 — DSA 🌳
Solved: Amount of Time for Binary Tree to Be Infected. Key idea:
→ HashMap: Node → Parent
→ BFS from the starting node
→ Track visited nodesBinary Tree + HashMap + BFS = clean solution.
Learning the pattern, not just the problem.

Day 1/21 �� DSA 🚀
Solved: All Nodes Distance K in Binary Tree 🌳
Key insight:
→ HashMap: Node → Parent
→ Move Left, Right & Parent
→ BFS to find nodes at distance K
→ Visited set prevents revisiting
Learning the concept, not just solving the problem.

@NickpxJ I built my first project using Codex, which was a great learning experience. I would appreciate your feedback on what key additions or refinements are needed to make this project valuable and production-ready -

Trying to grow my tech circle on X.

I’m a 3rd-year CSE student learning DSA,full-stack development .

Looking to connect with developers, engineers, students, founders, recruiters, and fellow builders.

Let’s learn, build, share projects, and help each other grow.
Let's connect!

From "What's a Pull Request?" to 19 merged PRs.

That's what 3 months of Open Source taught me.

The biggest reward wasn't the rank—it was becoming a more confident developer.

🚀 Just getting started.
