intermediate Published 14 Jun 2026
Action Steps
  1. Read the problem statement carefully to understand the requirements and constraints.
  2. Initialize two pointers, one at the start and one at the end of the sorted array.
  3. Compare the sum of the values at the two pointers with the target sum and adjust the pointers accordingly.
  4. Repeat the comparison and adjustment process until the target sum is found or the pointers meet.
  5. Implement the two pointers technique in a programming language, such as Python or Java, to solve the problem.
Who Needs to Know This

This technique is useful for software engineers, especially those working on algorithmic challenges or optimizing code for performance. It can be applied in various problem-solving scenarios, such as finding pairs of integers in an array that add up to a target sum.

Key Insight

💡 The two pointers technique can be used to find pairs of integers in a sorted array that add up to a target sum, with a time complexity of O(n).
