Process of inserting an element in stack is called ____________

Detailed Solution for Test: Stack Operations - Question 1

Push operation allows users to insert elements in the stack. If the stack is filled completely and trying to perform push operation stack – overflow can happen.

Test: Stack Operations - Question 2

In a stack, if a user tries to remove an element from an empty stack it is called _________

Detailed Solution for Test: Stack Operations - Question 2

Underflow occurs when the user performs a pop operation on an empty stack. Overflow occurs when the stack is full and the user performs a push operation. Garbage Collection is used to recover the memory occupied by objects that are no longer used.

Entries in a stack are “ordered”. What is the meaning of this statement?

Detailed Solution for Test: Stack Operations - Question 3

In stack data structure, elements are added one by one using push operation. Stack follows LIFO Principle i.e. Last In First Out(LIFO).

Consider the usual algorithm for determining whether a sequence of parentheses is balanced. The maximum number of parentheses that appear on the stack AT ANY ONE TIME when the algorithm analyzes: (()(())(()))?
Detailed Solution for Test: Stack Operations - Question 4

In the entire parenthesis balancing method when the incoming token is a left parenthesis it is pushed into stack. A right parenthesis makes pop operation to delete the elements in stack till we get left parenthesis as top most element. 3 elements are there in stack before right parentheses comes. Therefore, maximum number of elements in stack at run time is 3.

Test: Stack Operations - Question 5

What is the value of the postfix expression 6 3 2 4 + – *?
Detailed Solution for Test: Stack Operations - Question 5

Postfix Expression is (6*(3-(2+4))) which results -18 as output.

Test: Stack Operations - Question 6
Save

Process of removing an element from stack is called __________
Detailed Solution for Test: Stack Operations - Question 6

Elements in the stack are removed using pop operation. Pop operation removes the top most element in the stack i.e. last entered element.

Test: Stack Operations - Question 7
Save

Pushing an element into stack already having five elements and stack size of 5, then stack becomes ___________
Detailed Solution for Test: Stack Operations - Question 7

The stack is filled with 5 elements and pushing one more element causes a stack overflow. This results in overwriting memory, code and loss of unsaved work on the computer.

Test: Stack Operations - Question 8
Save

Which of the following is not the application of stack?
Detailed Solution for Test: Stack Operations - Question 8

Data transfer between the two asynchronous process uses the queue data structure for synchronisation. The rest are all stack applications.

Test: Stack Operations - Question 9
Save

Consider the usual algorithm for determining whether a sequence of parentheses is balanced. Suppose that you run the algorithm on a sequence that contains 2 left parentheses and 3 right parentheses (in some order). The maximum number of parentheses that appear on the stack AT ANY ONE TIME during the computation?
Detailed Solution for Test: Stack Operations - Question 9

In the entire parenthesis balancing method when the incoming token is a left parenthesis it is pushed into stack. A right parenthesis makes pop operation to delete the elements in stack till we get left parenthesis as top most element. 2 left parenthesis are pushed whereas one right parenthesis removes one of left parenthesis. 2 elements are there before right parenthesis which is the maximum number of elements in stack at run time.

Test: Stack Operations - Question 10
Save

Here is an infix expression: 4 + 3*(6*3-12). Suppose that we are using the usual stack algorithm to convert the expression from infix to postfix notation. The maximum number of symbols that will appear on the stack AT ONE TIME during the conversion of this expression?
Detailed Solution for Test: Stack Operations - Question 10

When we perform the conversion from infix to postfix expression +, *, (, * symbols are placed inside the stack. A maximum of 4 symbols are identified during the entire conversion.
