Day 21 of #SDESheetChallenge @takeUforward_ 🔍

Binary search:

• Median of 2 Sorted Arrays
• Kth Element of 2 Sorted Arrays
• Book Allocation — minimize max pages
• Aggressive Cows — maximize min distance

[Priti Chavan @saturo_2004]

Day 20 of #SDESheetChallenge
@takeUforward_
Aaj Binary Search:
M ka Nth Root
Matrix ki Median
Single Non-Duplicate
Rotated Array mein Search
>>Asli trick? Hamesha index nahi dhundte — kabhi value range mein search karo, kabhi sorted half se aadha space hata do.

[Priti Chavan @saturo_2004]

Day 19 #SDESheetChallenge @takeUforward_
🎨 Graph Coloring — assign M colors so no neighbors clash
🐭 Rat in a Maze — find all paths through a blocked grid
🔤 Word Break — segment a string using dictionary words

Backtracking is just structured brute force with an early exit

[Priti Chavan @saturo_2004]

Day 18 of #SDESheetChallenge @takeUforward_
♛ N-Queens — place queens with zero conflicts 🔢 Sudoku Solver — constraint-based cell filling 🔤 Unique Permutations — prune duplicates without a hash set
The pattern is always the same: place → recurse → undo

[Priti Chavan @saturo_2004]

Day 17 🚀
@takeUforward_ #SDESheetChallenge
Diving deeper into backtracking & recursion today:
• Combination Sum
• Combination Sum II
• Palindrome Partitioning
• Permutation Sequence

Consistency > intensity. Let’s keep building. 💪

[Priti Chavan @saturo_2004]

#SDESheetChallenge
Day 16:
• Coin Change — DP, bottom-up
• Assign Cookies — greedy, two pointers
• Subset Sum — 0/1 knapsack DP
• Subsets II — backtracking + dedup

🗓️ Day 15 – #SDESheetChallenge @takeUforward_
Solved:
• Meeting Rooms (max meetings)
• Minimum Platforms
• Job Sequencing with Deadlines
• Fractional Knapsack

Greedy problems are clicking better now — sorting first really is half the battle. Onward to Day 16! #DSA

🗓️ Day 14 – #SDESheetChallenge @takeUforward_

Solved today:
• Trapping Rainwater 🌧️
• Remove Duplicates
• Maximum Consecutive Ones
Arrays getting stronger day by day 💪
Still learning to handle edge cases better.

🗓️ Day 13 – #SDESheetChallenge
@takeUforward_
Solved: 3Sum

Sorting + Two pointers = 🧠💡
Avoiding duplicates was the real challenge.
Slowly getting comfortable with patterns.

#DSA

[Priti Chavan @saturo_2004]

🗓️ Day 12 – #SDESheetChallenge
@takeUforward_
Solved: Flatten Linked List
Focused on handling multiple pointers (next & child) and merging sorted lists.
Good practice for understanding complex linked list structures.
Learning to be more careful with implementation details.

[Priti Chavan @saturo_2004]

🗓️ Day 11 – #SDESheetChallenge

Reverse K group kiya aaj

Samajh aaya 👍
Implement kiya 👍
Explain karne bola… ❌😅
Step by step hi jeet hai 🚶‍♂️

🗓️ D10 – #SDESheetChallenge @takeUforward_

Linked List continues…

Delete node without head 🤡
Add 2 numbers 🤯
Me: “ab pointers samajh aa rahe hain”
Also me: still confusing next & https://t.co/whCyWtFtgo 😭

10 days done ✅
Consistency > Motivation 💪

[Priti Chavan @saturo_2004]

🗓️ Day 9 – #SDESheetChallenge @takeUforward_

Linked List today:
Pointer idhar gaya 👉
Next udhar gaya 👈
Main kaha gaya? 🤡
3 questions done ✅
Logic samajh aaya… thoda thoda 😭

[Priti Chavan @saturo_2004]

🗓️D8 – #SDESheetChallenge @takeUforward_

Solved 3 problems today:
Longest Subarray with Sum = K
Subarrays with XOR = K
Longest Substring Without Repeating Characters

Key learnings:
• Prefix Sum + HashMap
• Prefix XOR trick
• Sliding Window approach
Consistency > speed
#DSA

[Priti Chavan @saturo_2004]

🗓️ Day 7 – #SDESheetChallenge @takeUforward_

Problem: “Longest Consecutive Sequence”
Me: easy hai 🙂
DSA: “ruk ja bhai” 😈
1 question done ✅
Dimaag: still buffering… ⏳
Lesson: problem easy nahi hota,
tum jaldi confident ho jaate ho!
