Select the correct answerWhich of the given array element will return the top-of-the-stack-element for a stack of size N elements(capacity of stack > N)?OptionsS[N]S[N+1]S[N-2]S[N-1]

Which of the following array element will return the top-of-the-stack-element for a stack of size N elements(capacity of stack > N)?S[N-1]S[N]S[N-2]S[N+1]

Select the correct answerA 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?Optionspos ← −1pos ← 1pos ← N−1pos

If an array-based stack has a capacity of 10 and currently contains 7 elements, what is the index of the top element after pushing one more element onto the stack?a)9b)10c)7d)8

A single array A[1..MAXSIZE] is used to implement two stacks, The two stacks grow from opposite ends of the array. Variables top1 and top2 (top1 < top2) point to the location of the topmost element in each of the stacks, If the space is to be used efficiently, the condition for "stack full" is*2 points(top1 = MAXSIZE/2) AND (top2 = MAXSIZE/2 + 1top1 + top2 = MAXSIZE(top1 = MAXSIZE/2) or (top2 = MAXSIZE)top1 = top2 - 1

A stack is implemented using an array and the top is always pointing to the first position in the array. Assuming the stack is not empty, the time complexities of push() and pop() operations are:Group of answer choicesO(n) and O(1)O(1) and O(1)O(1) and O(n)O(n) and O(n)
