Question

Assume you have a stack implemented with single-linked nodes, that looks like this:
Grapefruit -> Peach -> Lime -> Apple -> Banana -> Pineapple
'top' is a reference variable that points to the node containing Grapefruit, and 'count' is an internal
int that holds the count of nodes (currently 6).
If you want to do pop operation, what is the pseudocode to achieve this?
create a String called temp
set temp's pointer to be the same as top's element pointer
set top's pointer to temp
decrement count
return temp
O create a String called temp
set temp's pointer to be the same as top's next pointer
set top's pointer to be the same as top's element pointer
decrement count
return temp

create single linked node called temp
set temp's element pointer to Peach
set top to point at temp
decrement count
return Grapefruit
create a String called temp
set temp's pointer to be the same as top's element pointer
set top's pointer to be the same as top's next pointer
decrement count
return temp
O create a String called temp
set temp's pointer to be the same as top's element pointer
set top's next pointer to be the same as top's next's next pointer
decrement count
return temp

Expert Solution

Step 1

As we know A singly linked list is a data structure that consists of a sequence of nodes, where each node contains an element and a reference (or "pointer") to the next node in the sequence. The first node in the list is referred to as the "head" node, and the last node in the list doesn't have a reference to another node, indicating the end of the list
