Day 8/100.
Dedicated today entirely to DSA revision on LeetCode. Cleared a massive block of classic problems to reinforce core algorithmic patterns, specifically focusing on:
Two Pointers
Sliding Window
Intervals
#100DaysOfCode#LeetCode#CompetitiveProgramming#Cpp
Day 7/100.
LeetCode: 3737. Count Subarrays With Majority Element I. Solved this counting problem focusing on subarray tracking and element frequency.
Codeforces: 1907B. YetnotherrokenKeoard. Handled the logic for processing the string efficiently.
#100DaysOfCode#Codeforces
Day 6/100.
LeetCode: Cleared a matrix multiplication problem in C++.
Codeforces: C - Train and Queries.Debugged and optimized through multiple TLEs before finally locking in the Accepted verdict.
Persistence is key.
#100DaysOfCode#LeetCode#Codeforces#Cpp
Day 5/100: Backend Architecture.
Built the real-time bidding engine for a MERN auction platform.
Implemented MongoDB transactions to ensure atomic bid and price synchronization.
Engineered a live bid feed using Server-Sent Events (SSE) over standard HTTP.

Day 4/100.
LeetCode POTD: 1189. Maximum Number of Balloons (Frequency mapping).
Codeforces: C - Make Equal Again & A - Game 23 (Debugged through TLE/WA to get the AC).
#100DaysOfCode#LeetCode#Codeforces#Cpp
Day 3/100.
Cleared problems across two platforms today:
LeetCode: 1833. Maximum Ice Cream Bars.
Codeforces: 2193C Replace and Sum.
#100DaysOfCode#LeetCode#Codeforces
Day 2/100.
LeetCode POTD: 1840. Maximum Building Height (Hard).
Solved in C++ using a two-pass sweep algorithm. Propagated height restrictions left-to-right, then right-to-left, before calculating the maximum peaks between valid points.
#100DaysOfCode#LeetCode#Cpp
Day 1 of 100: Codeforces Grind.
Locked in and solved three problems today:
That is two 1000-rated problems and one 1100-rated problem, all successfully cleared in C++. Focusing on clean execution and steady progression.
#100DaysOfCode#Codeforces#CompetitiveProgramming#Cpp
It is time to lock in. Today, I am officially starting a 100-Day DSA, Dev, and CP Challenge.
The focus for the next 100 days:
Advanced C++ Competitive Programming
Full-Stack Development (MERN + AI)
Interview Prep & System Design
Let's get to work. #100DaysOfCode#BuildInPublic
