Quantitative Aptitude and Logical Reasoning

Q1. Explain the difference between Array and a linked list.
Ans. 
Array is a fixed-size data structure with elements stored sequentially, while linked list is a dynamic data structure with elements stored non-sequentially.
• Arrays have fixed size, while linked lists can grow dynamically.

• Accessing elements in an array is faster (O(1)), while in a linked list it is slower (O(n)).

• Inserting or deleting elements in an array can be inefficient, as it may require shifting elements, while in a...read more

Q2. Implement a Stack Using Queue
Ans. 
Implement a Stack using Queue by using two queues and maintaining the order of elements.
• Use two queues to simulate stack operations - push, pop, top.

• For push operation, add the element to the first queue.

• For pop operation, move all elements from the first queue to the second queue, except the last element which is popped.

• For top operation, return the last element in the first queue.
