Q2. 2) implement stack using queue 3) return triplets with given target sum
Ans. 
Implement stack using queue and return triplets with given target sum
• To implement stack using queue, we can use two queues and alternate between them for push and pop operations

• For returning triplets with given target sum, we can use a nested loop and a hash set to store visited elements

• We can then iterate through the array and check if the difference between target sum and current element exists in the hash set
