Two Sum

Explore how to identify two array indices that add up to a target value without reusing indices. Understand problem constraints, validate your approach, and implement an efficient O(n) time and O(n) space solution to enhance your algorithm problem-solving skills.

We'll cover the following...

Statement

For the given array of integers arr and a target t, you have to identify the two indices that add up to generate the target t. Moreover, you can’t use the same index twice, and there will be only one solution.

Note: We will assume that the array is zero-indexed and the output order doesn’t matter.

Constraints:

  • 2≤2 \leq arr.length ≤103\leq 10^3
