Today Solved another Problem #Leetcode 268. Missing number and clear array patterns and also invests deep concentration to this problem in a different way
not the optimal approach but this is an my approach and i have to solve my idea ...coming back with a optimised approach

Day’s DSA ✅
LeetCode 283 – Move ZeroesLearned
why pointer discipline matters and how a clean O(n) overwrite approach beats swap-heavy https://t.co/TvQN0Yh0Fq problem, solid learning 💪
uses two approaches to solve the problem first is brute then Optimised
#DSA #LeetCode #Java

Day X of DSA 🚀
Solved Remove Duplicates from Sorted Array using Two Pointers.
Key learning:
• i → scans the array
• j → tracks position for unique elements
Focused on logic & patterns, not “beats %” 💯

DSA Win Today!

Solved LeetCode 1752 – Check if Array Is Sorted and Rotated ✅
Key insight: a sorted + rotated array has at most one break in non-decreasing order (including last → first comparison).
No sorting, just clean O(n) logic 💡

Today's Progress!

Solved Leetcode 75.Medium Sort colours or Dutch National Flag Problem
Understand Three Pointer Approach and In - place array positioning .
A clean in-place solution with O(n) time — great boost #DSA

[Abhay Pratap Singh @Codewith_Abhay]

#Today I solved some solid #DSA questions—

understood two-pointer techniques,
and cracked problems step-by-step on my own.
1)Move Zeroes : Classical Problem
2)Palindrome Check (Two Pointers)
3)Maximum Product of Two Elements in an Array

One day at a time.

Had a great experience participating in TechQuest 2025, organized by the BCA–O–CRATES Club of GLA University this November. 💻⚙️

It was an amazing platform to explore ideas, problem-solving, and teamwork in a tech-driven environment.

#Today's Problem #DSA
#leetcode 125. Valid Palindrome

Covering Edge Cases of Alphanumeric and Cases While Solving the Palindrome Problem

Solved using Two Pointer Approach

Also Solved #DBMS Question of Relational Algebra
and knowing about the concept of Projection and Selection

Today I tackled closure, superkeys, candidate keys & 2NF in DBMS:

✅ AD⁺ closure, AC as superkey
✅ Candidate keys: AB, BC
✅ 2NF: removed partial dependencies (B→D)
✅ Merged FDs when needed (A→C & AC→F → R(A,C,F))
✅ Done a bunch of Good and Tricky problems 💪
Score: 9/11

Recursion Practice – Today’s Problems

Solved 3 problems today 2 Basics of Recursion and another looping series
1️⃣ Print numbers from N to 1 using recursion.
2️⃣ Calculate sum of first N numbers in Series .
Simple yet powerful way to master recursion! 💻🔥

#100DaysOfCode #Java

[Abhay Pratap Singh @Codewith_Abhay]

Today, I built a solution to calculate the sum of divisors for numbers from 1 to n.
💡 For each number, I summed its divisors using a simple nested loop.
⚡️ Example: For n = 4, the total sum is 15 (1 + 3 + 4 + 7).
🔧 Next goal: Optimize using a sieve-like approach. #BuildInPublic
