Q1. Find the pair that sum equal to given number
Ans. 
Find two numbers in an array that add up to a specified target sum.
• Use a hash map to store numbers and their indices for quick lookup.

• Iterate through the array and check if target - current number exists in the map.

• Example: For array [2, 7, 11, 15] and target 9, return (2, 7).

• Time complexity is O(n) due to single pass through the array.
