Completed 365 days streak on leetcode.

Started not even knowing syntax properly, now solving hard problems with confidence.

consistency > motivation, you just gotta show up daily.

Day 341 of my LeetCode Daily Challenge streak 🔥💻

Today's pick: 3345. Smallest Divisible Digit Product I (Easy) — find the

Simple brute force: check each number's digit product starting from n
until we find a hit ✅

[Aditya Chauhan @Aditya_Ch_20]

500 questions solved on leetcode. me and leetcode are basically in a situationship at this point 😭 still can't solve DP live though, that's a whole different chapter #leetcode #dsa #softwareengineer #100DaysOfCode #tech #placements

200 days streak on LeetCode 🔥
just been showing up daily, some days more some days less, but kept it going. slow progress but progress

@UberIN_Support Still no specific reason or ticket number after 24+ hours on DM — can you confirm a timeline?

[Aditya Chauhan @Aditya_Ch_20]

Unlocked Knight on LeetCode.

Started with a lot of wrong answers and confusion, but kept showing up.

Feels good to see consistency paying off.

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 🏅

Day 180 ✅

Solved Number of Steps to Reduce a Number in Binary Representation to One.

Instead of converting the binary string to a big integer, I simulated the process from right to left.Logic I used:

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).
#LeetCode #DSA #Java #BinaryTree #CodingJourney

[Aditya Chauhan @Aditya_Ch_20]

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 💻

#LeetCode #DSA #Java #SlidingWindow #CodingJourney

[Aditya Chauhan @Aditya_Ch_20]

Solved today’s LeetCode Daily Challenge!

Used a simple nested loop approach to try all valid split points and calculated the minimum cost efficiently.
Clean logic + optimal checks = accepted solution

#LeetCode #DSA #Java #ProblemSolving #CodingJourney

[Aditya Chauhan @Aditya_Ch_20]

LeetCode Daily done!🔥

Solved “Find Smallest Letter Greater Than Target” using Binary Search in Java.

Clean logic, fast execution (0ms⚡),
and wrapped up with the DCC January 2026 badge 🏅

#LeetCode #DSA #Java #CodingJourney #100DaysOfCode #DailyPractice #LearningInPublic

[Aditya Chauhan @Aditya_Ch_20]

LeetCode Daily done!🔥
Solved Minimum Cost Path with Teleportations today — a challenging DP + optimization problem.
Loved combining grid traversal with teleport mechanics and minimizing cost efficiently.
