Day 1/45 of #SDESheetChallenge 🚀
Solved:
✅ Set Matrix Zeroes
✅ Pascal's Triangle I
✅ Next Permutation
Biggest learning:
Understanding in-place optimization and lexicographical ordering.
Every day = 1% better.

📆Day 4/45 of #SDESheetChallenge
Done:
✅ Find the Duplicate Number
✅ Find the Repeating and Missing Number
✅ Inversion of Array
Today's problems were challenging, especially Inversion Count.
Took help from Striver's 🫡videos to understand the intuition and optimal solutions.
Day 6/45 ✅
Today's problems:
• Majority Element II
• Unique Paths
• Reverse Pairs
Reverse Pairs was the toughest one today. Ngl, if an interviewer asks this and you've never seen it before, you're probably cooked 💀.

Day 6 of #SDESheetChallenge by @takeUforward_ 🚀
✅ Majority Element II
✅ Grid Unique Paths
✅ Reverse Pairs
Today's highlight: Reverse Pairs. Another reminder that Merge Sort can do much more than just sorting. 😄
On to Day 7 💪
#DSA#LeetCode#StriversSheet
Started my #SDESheetChallenge today! 🚀
Day 1 Progress:
Pascal's Triangle: Build solutions row by row
Next Permutation: Think in terms of permutations and pivots
Set Matrix Zeroes: Optimize space using matrix markers
