🗂️ Topics

1. Basic DSA

1. Array → Operations in Array, Largest Element, Second Largest Element, Reverse an Array, Check if Array is Sorted, Remove Duplicates, Left Rotate Array, Move Zeros to End
2. Recursion → Natural Number, Palindrome Number, Sum of Digits, Rope Cutting, Generate Subsets (no need Tower of Hanoi)
3. Hashing → Only theory, no need to solve any questions
4. Searching → Simple Search, Binary Search [Recursion + Iterative], Ternary Search (if want)
5. Sorting → 5 main sorts + Hash Sort (only see, no need to remember)
6. Linked List
   • i. Singly → Traverse, Search, Insert, Delete, Reverse
   • ii. Doubly → Insert, Delete, Reverse
   • iii. Circular → Traverse, Insert, Delete
7. Stack → Implement using Array and using Linked List
8. Queue → Using Array, using Linked List
9. Dequeue → Array-based Implementation
10. Tree → Traversal, Level Order, Max, Size, Height
11. BST → Search, Insert, Deletion, Ceil, Floor
12. Heap → Insertion and Heapify (properly understand)
