What is the difference between stack and heap memory?

Step by step
Solved in 2 steps
- How would you design a stack which, in addition to push and pop, also has a function min which returns the minimum element? Push, pop and min should all operate in O(1) time. Your design (in pseudo code) should include a class Stack and three functions, i.e., push, pop, and min.S1 and S2 are two sorted stacks of n and m numbers, with the top elements of each stack pointing to the smallest number in their list. To ensure that all of the components in stacks S1 and S2 are available in MERGE in decreasing order, with the largest element at the top, create a stack MERGE that combines the items in stacks S1 and S2.Remember that there are (n + m) components in the stack MERGE.In Go Lang 4. Program stack. For the following code, answer the following questions. Assume we are putting everything for our function calls on the stack. · Show what a stack frame/activation record for main() looks like · Show what the stack frame/activation record for the 2nd call to ctTarg look like? (Yes, this means you can skip the other stack frames) · We note that targ does not change value in any recursive call. Why doesn't the compiler just store targ once in one block of memory big enough to store a string? int ctTarg(string* list, int len, string targ) { if (len <= 0) return 0; if (*list == targ) return 1 + ctTarg(list + 1, len - 1, targ); return ctTarg(list + 1, len - 1, targ); } int main() { string pets[] = {"cat", "dog", "mouse", "cat"}; cout << ctTarg(pets, 4, "cat") << endl; }
- Please explain the difference between Stack and Heap. Including data on the frame pointer, the stack pointer, and other relevant variables.Write the program by completing the main program that doesthe following:1. Call the push function three times.2. Prints out the updated stack3. Calls the pop function once4. Print the updated stack again.No need to write the algorithm for this problem, it is already given to you.#include <stdio.h>#define STACK_EMPTY '0'#define STACK_SIZE 20voidpush(char stack[], /* input/output - the stack */char item, /* input - data being pushed onto the stack */int *top, /* input/output - pointer to top of stack */int max_size) /* input - maximum size of stack */{if (*top < max_size-1) {++(*top);stack[*top] = item;}}charpop (char stack[], /* input/output - the stack */int *top) /* input/output - pointer to top of stack */{char item; /* value popped off the stack */if (*top >= 0) {item = stack[*top];--(*top);} else {item = STACK_EMPTY;}return (item);}intmain (void){char s [STACK_SIZE];int s_top = -1; // stack is empty/* complete the program here */return (0);}10.3 Suppose you wish to fill a stack with a copy of another, maintaining theorder of elements.

- Can you please explain this code to me step-by-step? I especially did not get how s.append(x) is iteratively adding the elements back to the stack without any loop. Note: If you can spot any mistake in the function call, please point that out as well. CODE To Delete Middle Element of a Stack: def deleteMid_util(s, sizeOfStack, current): #if current pointer is half of the size of stack then we #are accessing the middle element of stack. if(current==sizeOfStack//2): s.pop() return #storing the top element in a variable and popping it. x = s.pop() current+=1 #calling the function recursively. deleteMid_util(s,sizeOfStack,current) #pushing the elements (except middle element) back #into stack after recursion calls. s.append(x) def deleteMid(s, sizeOfStack): deleteMid_util(s, sizeOfStack, 0) res = deleteMid([1,2,3,4,5], 5) print(res)I'm preparing my study material to study for an upcoming test, I was wondering if you can help me provide a short but sweet way of memorizing these topics, regarding Stack:what is postpone obligations and what are the advantages/disadvantages of using Stack? If this counts as 2 questions and I need to choose only one, understanding what postpone obligations would be my question please.Need help in Stack/Queue Which of the following statements are correct about the time complexity of the operations of Queue implementations? If not, why? (ex. if 1 is incorrect, write fixed version, like dynamic array is used for implementation) If a circular array is used for implementation, the dequeue operation has a time complexity of O(n). If an array is used for the implementation with the first element in the queue always stored in index 0 of the array, the time complexity of the dequeue operation is O(n). If an array is used for the implementation with the first element in the queue always stored in index 0 of the array, the worst-case time complexity of the enqueue operation is O(n).
- Code in C One of the applications of a stack is to backtrack - that is, to retrace its steps. As an example, imagine we want to read a list of items, and each time we read a negative number we must backtrack and print the five numbers that come before the negative number and then discard the negative number. Use a stack to solve this problem. Use a stack and push them into the stack (without printing them) until a negative number is read. At this time, stop reading and pop five items from the stack and print them. If there are fewer than five items in the stack, print an error message and stop the program. After printing the five items, resume reading data and placing them in the stack. When the end of the file is detected, print the message and the items remaining in the stack. Sample Output 1 2 3 4 5 6 7 -1 7 6 5 4 3 9 6 4 3 -2 3 4 6 9 2 -3 Number of items left is less than five! Program is terminating! Project name : Backtrack Filenames: backtrack.h, backtrack.c,…I am writing a stack code, where there are two stacks that reads an array of 40 numbers and puts them in ascending and descending order. I put my code on the bottom. The requirements of the code was to write the stack functions using arrays, but whenever i run the code it does not work. However, if use stack in built function the code works. Help me please. PS: I Attached the code requirements. struct Stack1 { int *arr; int NextIndex; int capacity; Stack1() { capacity = 20; arr = new int[capacity]; NextIndex = 0; } int size () { return NextIndex; } bool isEmpty() { if (NextIndex == 0) { return true; } else return false; } void push(int ele) { if (NextIndex == capacity) { int *newArr = new int[2*capacity]; for(int i = 0; i < capacity; i++) {…Please explain the distinction between the restricted version of the stack and the unlimited version of the stack.
