Answer:
Stack.
Explanation:
Topological sort requires a bit of addition to DFS algorithm.So DFS can be done by two ways that are either you can use recursion or you can use Stack data structure to implement DFS.
Since recursion uses stack memory when it makes recursive calls and if you want to do it iteratively you can stack data structure.
Answer:
The answer is "Option a"
Explanation:
A method is a technique, that associated with both a message and an object. It includes information, behavior, and actions of an interface defining, how the object can be used, and wrong choices can be described as follows:
- In option b, It includes parameters in the method.
- In option c, It contains a parameter, that may be one or more.
- In option d, It contains one parameter also.
It is true that in the array implementation of a queue, the pop operation is most efficient if the front of the queue is fixed at index position. The correct option is a.
<h3>What is pop operation? </h3>
The removal of an element is referred to as a pop operation. Again, because we only have access to the element at the top of the stack, we can only remove one element. We simply take the top of the stack off.
A push operation decrements the pointer before copying data to the stack; a pop operation copies data from the stack before incrementing the pointer.
The pop operation in an array implementation of a queue is most efficient if the queue's front is fixed at index position.
Thus, the correct option is a.
