Question
How to call sum function from main in LEGv8 assembly code:
int f, g, y
int sum (int a, int b) {
return (a +b)
}
int main (void)
{
f=2;
g=3;
y= sum (f, g);
return y;
}
Explain each line, and use only conventional commands. Is it possible to use stack in this example? First we push using SUBI and store them using STUR.

- Suppose in an implementation of STACK supports an instruction REVERSE which reverses the order of the elements on the STACK, in addition to the PUSH and POP instructions. Which following statements is/are TRUE with respect to this modified STACK? Please discuss each of these statements on why that statement is True/False. a) a Queue can be implemented where ENQUEUE takes a single instruction and DEQUEUE takes a sequence of two instructions. (If this statement is true, please show how to implement it. If False, Please Explain Why?)arrow_forwardWrite an Arm Assembly Program that does the following:•Stores on the stack a list of words of memory where the first element of the list is how manyremaining elements are in the list, and the rest of the elements in the list are initialized tosome random values.– Example:list: 6, -3, 4, 5, 9, 22, 99//stores a list of the 6 elements -3, 4, 5, 9, 22, 99•At the end of the program, register r0 should hold the sum of only the negative values in thearray (nonnegative elements are ignored).•Note that your program must work correctly even if the values stored in the list are changed.arrow_forwardConsider a standard stack data structure with a push and popoperation. What would be the exact complexity (not Big O) to print alln items in some stack and return it to its original order when finished?arrow_forward
- Answer the following two questions correctly. This is in Python. Explain your reasoning.arrow_forwardInstructions C++ a. Add the following operation to the class stackType. void reverseStack(stackType<Type> &otherStack); This operation copies the elements of a stack in reverse order onto another stack. Consider the following statements: stackType<int> stack1;stackType<int> stack2; The statement stack1.reverseStack(stack2); copies the elements of stack1 onto stack2 in reverse order. That is, the top element of stack1 is the bottom element of stack2, and so on. The old contents of stack2 are destroyed, and stack1 is unchanged. b. Write the definition of the function template to implement the operation reverseStack. Write a program to test the class stackType. myStack.h //Header file: myStack.h #ifndef H_StackType #define H_StackType #include <iostream> #include <cassert> #include "stackADT.h" using namespace std; template <class Type> class stackType: public stackADT<Type> { public: const stackType<Type>&…arrow_forwardThe solution is provided.
