Question
The required condition which is checked before insertion in a linked queue is?
Options
- Overflow
- Underflow
- Front value
- Rear value
Solution
The condition that is checked before insertion in a linked queue is Overflow.
Here's why:
-
In a linked queue, we insert elements at the rear and remove elements from the front.
-
Before insertion, we need to check if there is enough space in the queue to accommodate the new element. This is because, unlike arrays, linked lists do not have a fixed size. They can grow and shrink dynamically.
-
The condition of 'Overflow' refers to the situation when the queue is full and no more elements can be added.
-
Therefore, before inserting a new element, we need to check if the queue is already full. If it is, we say that an 'Overflow' condition has occurred.
-
If the queue is not full, we can proceed with the insertion.
-
The conditions of Underflow, Front value, and Rear value are not checked before insertion in a linked queue. Underflow refers to the situation when the queue is empty and we are trying to remove an element. Front value and Rear value are the values of the front and rear elements of the queue, respectively. They do not affect the insertion operation.
