- we get a stack of chars. The implementation is given in a separate file. You should not make assumptions about the exact implementation details. You may only use the following functions to access the stack. typedef struct { // not known } stack_t; // creates a new stack stack_t* stack_create(); // pushes a given item to the stack void stack_push(stack_t* s, char item); // pops the top element from the stack // Pre condition: stack is not empty char stack_pop(stack_t* s); // checks if the stack is empty bool stack_is_empty(stack_t* s); // frees the stack void stack_free(stack_t* s); a) Write a function that gets a stack of ints and returns the number of elements in it. When the function returns, the stacks must be in their initial state. // returns the size of the stack int stack_size(stack_t* s) b) Write a function that gets two stacks of ints and checks if they are equal (i.e., have the same elements in the same order). When the function returns, the stacks must be in their initial…You are allowed to operate on a stack WORK and a temporary stack TEMP (ifneeded) supporting their ADT operations of PUSH (S,X), POP (S, X) andEMPTYSTACK (S) only, where X represents an element/variable to be pushed in orpopped out of the stack and S represents a stack. You are also permitted to use one variable if needed to carry out the operations. i) Given n distinct random numbers that are to be pushed into WORK, how canyou find the maximum element that was pushed into it, all the while ensuring thatthe elements stored in WORK are in their descending order with the maximumelement beginning at the bottom of stack? You are permitted to use a lone variableand a temporary stack TEMP.ii) Given an array A[1: n] of distinct random numbers how can you obtain thesorted list in the array, making use of stacks alone?Would you kindly explain the distinction between the restricted and unbounded versions of the stack?
- A SpecialStackTM is a stack modified to support the following two operations: PUSHCLEAR(v) successively pops consecutive items from the top of the stack that are less than u, then pushes v onto the stack. POP() deletes the item at the top of the stack. Assume these operations are implemented using a singly-linked list. PUSHCLEAR(v) iter- ates through the linked list to pop the applicable items and then adds v to the beginning. POP() deletes the first item. (a) Describe the ordering of values on the stack. (b) Explain how a single call to PUSHCLEAR(V) could take (n) time. (c) If we assume that every operation takes linear time, we get a naive bound of O(n²) on the total runtime. But this doesn't consider the fact that these expensive operations happen infrequently so let's analyze it more closely. Show that any sequence of n operations takes O(n) time. -Please explain the distinction between the restricted version of the stack and the unlimited version of the stack.Determine how the stack behaves when it is permitted to operate on its own.
- You are allowed to operate on a stack WORK and a temporary stack TEMP (ifneeded) supporting their ADT operations of PUSH (S,X), POP (S, X) andEMPTYSTACK (S) only, where X represents an element/variable to be pushed in orpopped out of the stack and S represents a stack.

You are permitted to use alone variable.ii) Given n distinct random numbers that are to be pushed into WORK, how canyou find the maximum element that was pushed into it, all the while ensuring thatthe elements stored in WORK are in their descending order with the maximumelement beginning at the bottom of stack? You are permitted to use a lone variableand a temporary stack TEMP.iii) Given an array A[1: n] of distinct random numbers how can you obtain thesorted list in the array, making use of stacks alone?You may only operate on the stacks WORK and TEMP, supporting their ADT operations of PUSH (S, X), POP (S, X), and EMPTYSTACK (S), where X is an element or variable to be pushed into or popped out of the stack and S denotes the stack itself. If necessary to complete the procedures, you may also utilise one variable.i i) I How can you determine the least element that was put into Work given n different random numbers? You may employ a single variable. ii) Given n distinct random numbers that are to be pushed into WORK, how canyou find the maximum element that was pushed into it, all the while ensuring thatthe elements stored in WORK are in their descending order with the maximumelement beginning at the bottom of stack? You are permitted to use a lone variableand a temporary stack TEMP.• A stack is initially empty. Show the contents of this stack on execution of each of thefollowing operations: push('Jan'), push('Feb'), pop(),push('Mar'), pop(), pop().What will happen if another pop() operation is invoked after the execution of the above sequence of operations?
