Which function can combine the functionalities of push, pop, unshift and shift? Correct Answer splice

The splice function can perform all the four functions performed by these functions. It uses upto four arguments to add or remove elements at any location of the array. The second argument is the offset from where we’ve to perform insertion or deletion, the third argument represents the number of elements to be removed. If it is 0, elements are to be added. The fourth argument specifies the new replaced list. For example, @list= (1,2,3,4,5,9) ; splice(@list, 5, 0, 6. . 8); //adds at 6th location -1,2,3,4,5,6,7,8,9

A stack is implemented with an array of ‘A [0..N – 1]’ and a variable ‘pos’. The push and pop operations are defined by the following code. push(x)                 A[pos] ← x                 pos ← pos – 1 end push pop( )                 pos ← pos + 1                 return A[pos] end pop Which of the following will initialize an empty stack with capacity N for the above implementation?

The shift register shown in the figure is initially loaded with the bit pattern 1010. Subsequently, the shift register is clocked, and with each clock pulse the pattern gets shifted by a one-bit position to the right With each shift, the bit at the serial input is pushed to the leftmost position (MSB) After how many clock pulses will the content of the shift register become 1010 again?
A Double-ended queue supports operations such as adding and removing items from both the sides of the queue. They support four operations like addFront(adding item to top of the queue), addRear(adding item to the bottom of the queue), removeFront(removing item from the top of the queue) and removeRear(removing item from the bottom of the queue). You are given only stacks to implement this data structure. You can implement only push and pop operations. What are the total number of stacks required for this operation?(you can reuse the stack)
