#Day20 of Strike DSA GenAI by @rohit_negi9
What I Learned Today:
Learned Space Complexity and Selection Sort
🔹 Understood in-place vs extra space
🔹 Learned how Selection Sort works and why it is O(n²)

Lecture 12 of STRIKE DSA
Covered space complexity and sorting algorithms:
• Extra space matters as much as time
• Selection Sort: simple approach, fixed numbers of comparison

✅35/100
Just solved "Valid Palindrome" .🚀
My first regex-based solution worked, but it took O(n) space. The real win was refactoring it with a two-pointer approach to get that with O(1) space 😇
Thanks @akshaymarch7 🙏
