Another small milestone

Just earned the LeetCode 100 Days Badge 2026 for solving problems consistently this year.

Trying to show up every day, learn something new, and get a little better at problem solving. The journey continues

Sharing a small update

Participated in Google Big Code 2026
→ Top 15k (Qualifier)
→ Top 1.5k (Round 1)
→ Reached Round 2
Didn’t make finals this time, but learned a lot about problem-solving and handling pressure.

Will come back stronger.

Day 185 ✅

Solved Find Kth Bit in Nth Binary String using recursion.
Used the pattern: Sₙ = Sₙ₋₁ + "1" +
reverse(invert(Sₙ₋₁)).Checked middle index, recursed on left half, or mirrored and inverted for right half.

Day 182 ✅

Solved Concatenation of Consecutive Binary Numbers.

Used bit shifting to append each number’s binary form and applied modulo at every step to avoid overflow.

Also received DCC February 2026 badge 🏅

Got my 50 Days Badge 2026 on LeetCode 🎯

50+ days of consistently solving problems this year.

From struggling with basic patterns to now comfortably applying binary search, sliding window, DFS, and DP where needed.

Balanced Binary Tree ✅
(Day 162)Solved today’s LeetCode using DFS.

Calculated height of left and right subtrees and returned -1 early if the difference > 1.

This bottom-up approach avoids repeated traversal and keeps it O(n).

Solved today’s LeetCode Daily ✅ (Minimum Removals to Balance Array)

Approach:
Sorted the array first, then used two pointers to find the longest valid window where
max ≤ min × k.

O(n log n) | Java 💻
