Which of the following is FALSE?AYou need to perform one or more pop() operations to display the content of non-empty stackBYou need to set counter to increase by 1 every time a new data is added into the queue. CYou need to update the tail value every time remove operation is performed on a queueDYou need use Stack to solve problems that require LIFO concept to be implemented on a group of data.

An implementation of a queue Q, using two stacks S1 and S2, is given below:void insert(Q, x) {   push (S1, x);}  void delete(Q){   if(stack-empty(S2)) then      if(stack-empty(S1)) then {          print(“Q is empty”);          return;      }      else while (!(stack-empty(S1))){          x=pop(S1);          push(S2,x);      }   x=pop(S2);}Let n insert and m (<=n) delete operations be performed in an arbitrary order on an empty queue Q. Let x and y be the number of push and pop operations performed respectively in the process. Which one of the following is true for all m and n?n+m <= x < 2n and 2m <= y <= n+mn+m <= x < 2n and 2m<= y <= 2n2m <= x < 2n and 2m <= y <= n+m2m <= x <2n and 2m <= y <= 2n

Which of the following is not part of the pop operation for a stack implemented using a linked list? A. adjust the top reference variable to point to the node pointed to by the next field of the node at the top of the stack B. declare a temporary reference variable and set it to point to the element at the top of the stack C. all of these are part of the pop operation for a stack implemented using a linked list D. determine if the stack is empty E. determine if the stack is full

A stack is implemented with an array of 'A [0..N - 1]' and a varlable 'pos'. The push and pop operations are defined by the following code.push(x) A[pos] ← X pos ← pos - 1end pushpop( ) pos ← pos + 1 return A[pos]end popWhich of the following will initialize an empty stack with capacity N for the above Implementation?
