Understanding basic data structures and algorithms is crucial for coding interviews.

• Data Structures: Arrays, Linked Lists, Stacks, Queues, Trees, Graphs.

• Algorithms: Sorting (e.g., Quick Sort, Merge Sort), Searching (e.g., Binary Search).

• Complexity Analysis: Big O notation to evaluate performance.

• Example: Use a stack to reverse a string efficiently.
