Q2. Two sum- return true or false
Ans. 
Given an array of integers, determine if there are two numbers that add up to a specific target.
• Iterate through the array and store each element in a hash set.

• For each element, check if the difference between the target and the element exists in the hash set.

• If the difference exists, return true; otherwise, continue iterating.

• Example: nums = [2, 7, 11, 15], target = 9. The function should return true as 2 + 7 = 9.
