Thought I had solved Word Break with recursion... until LeetCode introduced me to TLE 😅

Spent some time understanding why it was slowing down and eventually got it accepted using a Queue (BFS) approach.

Every problem teaches something new.

Day 19/45 of #SDESheetChallenge

✅ M Coloring Problem
✅ Rat in a Maze
✅ Word Break

Not every path leads to the answer... but every wrong path teaches something.
Backtracking, recursion, and a lot of trial-and-error.

Day 18/45 of #SDESheetChallenge

✅ Permutations of a String
✅ N-Queens
✅ Sudoku Solver

A full day of backtracking.
Tried a path.
Hit a dead end.
Went back.
Tried again.
Turns out that's how both backtracking and learning DSA work.😅

I grew up watching heroes on screen.

Then I came across the journey of K. Annamalai.

Farmer's son ➝ Engineer ➝ IIM graduate ➝ IPS officer ➝ Public servant.

That's when I realized real heroes exist too. 🔥❤️

Day 13 of #SDESheetChallenge ✅

Solved:
• Rotate List
• Copy List with Random Pointer
• 3Sum

3Sum taught me patience.
Random Pointer taught me confusion.
Rotate List taught me that Linked Lists can always get weirder. 😂

Progress > Perfection .

Got Accepted.
Felt smart.
Saw the optimal solution.
Felt humbled. 😂

Anyone else have a problem that made them question all their life choices after seeing the editorial?

Solved:
✅Palindrome Linked List
✅Linked List Cycle II
✅Flattening a Linked List

Linked Lists have taught me one thing:
One wrong pointer = 30 minutes of debugging 😭
