This looks like a variation of the Two Sum problem. You can solve it in O(n) time using a hash map. Let me show you the Python code: 
def two_sum(nums, target):
    seen = {}
    for i, num in enumerate(nums):
        if target - num in seen:
            return [seen[target - num], i]
        seen[num] = i
⚡ Explanation:
This function solves the Two Sum problem in linear time O(n) using a dictionary:
  • seen is a dictionary that keeps track of numbers we've already encountered and their indices.
  • For each number in the list, we compute the difference between the target and the current number.
  • If that difference is already in seen, we found the pair — return both indices.
  • Otherwise, store the current number and its index in the dictionary for future lookups.
  • This avoids using nested loops and ensures the algorithm runs efficiently, even on large lists.
