DSA Pattern: Two Pointer Technique
Master the two pointer pattern for efficient array and string manipulation
Pattern Overview
When to Use
- Sorted arrays
- Finding pairs with target sum
- Removing duplicates
- Palindrome detection
Benefits
- O(n) time complexity
- O(1) space complexity
- Efficient for large datasets
- Reduces nested loops
Example Problems
Two Sum (Sorted Array)
Find two numbers that add up to target
Remove Duplicates
Remove duplicates in-place from sorted array
