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