- 1. For the code below, draw a picture of the program stack when the function partition() is called the first time. You only have to draw the part of the stack for quicksort() and partition(). # extracted from suquant's reply at # https://stackoverflow.com/questions/18262306/quicksort-with-python def partition(array, begin, end): pivot = begin for i in range(begin+1, end+1): if array[i] <= array[begin]: pivot += 1 array[i], array[pivot] = array[pivot], array[i] array[pivot], array[begin] = array[begin], array[pivot] return pivot def quicksort(array, begin, end): if begin >= end: return pivot = partition(array, begin, end) quicksort(array, begin, pivot-1) quicksort(array, pivot+1, end) # added calling code if __name__ == "__main__": mylist = [8, 2, 17, 4, 12] quicksort(mylist, 0, 4)1. a) When a function is called in a given running program, an _____________ is created in the stack section of the virtual address space of the program that stores all the variables local to the function 1.b) Will the code below change the value of x? Explain why your answer is correct. All codes in c++ #include <iostream> using namespace std; void change(int); int main() { int x = 10; change(x); cout << "x = " << endl; return 0; } void change(int n1) { n1++; }(a)Write the CF and OF flag valuesmov al,-128neg al ; CF = OF =mov ax,8000hadd ax,2 ; CF = OF =mov ax,0sub ax,2 ; CF = OF =mov al,-5 sub al,+125 ;CF= OF =(b)In the following figure after pupping the top two values of the stack , the stack pointer points towhich next location in the stack . Highlight the address of that specific location BEFORE 00001000 00000006 00000FFC 000000A5 00000FF8 00000001 00000FF4 00000002 ESP 00000FF0
- a) Given the table and rules above, as well as the following state stack and input: STATE/STACK --> 0T2*7(4E8+6T9 INPUT --> )$ What is your next string in the Stack? b) STATE/STACK --> 0T2*7F INPUT --> $ What is your next string in the Stack? c) STATE/STACK --> 0 INPUT --> -id$ What is your next string in the Stack?// the language is c++, please code with common for better understanding, and after your code finished take a screenshot of the execution. Write a C++ program to simulate a stack using an array. You should create an index (the stack pointer) to point into the stack. Initialize it to 0. The stack should grow to location [1], [2], [3], etc. Write a "push (int)" function to push an int onto the top of the stack. Also, write an "int pop" instruction to pop the data that is stored on the top of the stack. The pop instruction must return the popped data. The push and pop instructions should increment and decrement the stack pointer appropriately. Your source should contain calls to your functions demonstrating that it works. Note, that you should do several pushes and several pops to show that data is correctly stored on the stack. You can do this by showing sample runs. Cut and paste the results of the runs into a separate documentSuppose you wanted a subroutine to return to an address that was 3 bytes higher in memorythan the return address currently on the stack. Write a sequence of instructions that would beinserted just before the subroutine’s RET instruction that accomplish this task.
- What if a stack resource cannot be created?56. What is the stack pop operation? Group of answer choices The pop operation reads and discards the next character from the input stream. An istream processes characters in the order they are received. The pop operation reads and discards the next character from the input stream. A stack processes characters in the LIFO fashion. The pop operation reads and discards the first character from the input stream. A stack processes characters in the LIFO fashion. The pop operation reads and discards the last character from the input stream. An istream processes characters in the order they are received. The stack top operation reads and discards the next character from the input stream. An istream processes characters in the order they are received.q5) Which of the following is not true about stack data structure? a. Stack is data structure which stores data in last in first out method. b. Stack is a logical structure defined in the main memory. c. Stack can be implemented by arrays and linked list. d. Stack is a data structure which stores data in first in first out method.
