Consider the following pseudo-code to perform push and pop operation on a stack using enqueue(EQ) and dequeue(DQ) operations on 2 queues q1 and q2. Let x be an element to be pushed in the stack. answer the following questions.
push(q1,q2,x)
{
if(q1 is empty)
{
EQ(q2,x);
}
Else
{
EQ(q1,x);
}
}
pop(q1, q2)
{
if (q1 is empty)
{
if (q2 is empty) 

print “stack underflow”;
Exit;
}
else
{
while(q2 does not contain one element)
{
k= DQ(q2);
EQ(q1,k);
}
Return (DQ(q2));
}
}
Else
{
while(q1 does not contain one element)
{
k= DQ(q1);
EQ(q2,k);
}
Return (DQ(q1));
}
}
If we perform 8 push and 2 pop operations on the above algorithm then total how many enqueue and dequeue operations are performed on queues?
    Correct answer is '36'. Can you explain this answer?

    Consider the following pseudo-code to perform push and pop operation o...
    The pseudo-code provided is incomplete, as the closing parenthesis for the "print" statement is missing. However, based on the given code, we can infer that the missing code is "Stack is empty." Therefore, the complete code for the pop operation would be:

    pop(q1, q2){
    if (q1 is empty){
    if (q2 is empty){
    print "Stack is empty.";
    }
    else{
    while (size of q2 is greater than 1){
    EQ(q1, DQ(q2));
    }
    print DQ(q2);
    }
    }
    else{
    while (size of q1 is greater than 1){
    EQ(q2, DQ(q1));
    }
    print DQ(q1);
    }
    }

    This code checks if q1 is empty. If q1 is empty, it checks if q2 is also empty. If both q1 and q2 are empty, it prints "Stack is empty." Otherwise, it transfers all the elements from q2 to q1, except the last element, and then prints the last element. If q1 is not empty, it transfers all the elements from q1 to q2, except the last element, and then prints the last element.

    8 push operation is equivalent to 8 EQ operation.
    2 pop operation is equivalent = 1st pop and 2nd pop one after the other
    1st pop operation = (7 DQ(q1) + 7 EQ(q2) + 1 DQ(q1) )
    2nd pop operation = (6 DQ(q2) + 6 EQ(q1) + 1 DQ(q2) )
    Total =8EQ+ 15 DQ + 13 EQ = 36
    Hence the correct answer is 36.
