What I Changed (Read these aloud)

The current solution uses nested loops, resulting in O(n²) time complexity.
We can optimize this by using a hash map to store previously seen numbers.
This reduces time complexity to O(n) with O(n) space trade-off.

Solution

1def twoSum(nums: List[int], target: int) -> List[int]:
2    seen = {}  # Value -> Index mapping
3    for i, num in enumerate(nums):
4        complement = target - num
5        if complement in seen:
6            return [seen[complement], i]
7        seen[num] = i
8    return []  # No solution found

Complexity

Time Complexity: O(n)
Space Complexity: O(n)
