Day 12 of #100DaysOfCode 🚀
[~4 hours grind]
Today solved from @leetcode:
✅ Validate Binary Search Tree
>Used Min/Max range validation
>Checked every node against valid bounds
>Learned why checking only parent nodes isn't enough
✅ Recover Binary Search Tree
>Used Morris Inorder Traversal (O(1) space)
>Recovered the BST by swapping the incorrect values
>Every BST has a story—today I learned how to fix one. 🌳🚀
