Assertion (A): While working with Stacks, the program should check for Overflow condition before executing push operation and, similarly, check for Underflow before executing pop operation.
Reasoning (R): In Stack, Underflow means there is no element available to remove and Overflow means no further element can be added to it.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
Both A and R are true and R is the correct explanation of A.
Explanation
To use a Stack efficiently, it's crucial to check its status by examining overflow conditions before executing a push operation and underflow conditions before executing a pop operation. In a stack, underflow occurs when there are no elements available to remove (e.g., trying to pop from an empty stack), while overflow happens when there's no more space to add elements (e.g., trying to push onto a full stack).

Assertion (A): The major implementation of using a data structure is to manage the storage of data in the memory efficiently.
Reasoning (R): Data structure refers to the way memory is allocated for holding data using minimum space. It leads to faster data access during the execution of the program.
