The Two Pointers pattern is a powerful DSA technique used to solve array, string, and linked list problems efficiently.
Instead of using nested loops, we use two pointers moving in different directions to reduce time complexity.
This pattern is commonly used in problems involving sorted arrays, pair finding, sliding windows, and linked lists.
It helps optimize brute-force solutions from O(n²) to O(n) in many cases.
Mastering Two Pointers is very important for coding interviews and placement preparation.
