The following is a sequence of stack operations S1.push (12); S1.push (-5); Int t1 = S1.pop(); S1.push (-8); S1.push (20); Int t2 = S1.topValue(); S1.pop (); S1.push (4); I. Assuming all instructions execute in the given sequence, draw four diagrams, showing the contents of the stack, after executing the second, fourth, sixth, and eighth instructions. In each diagram, include the values of all elements in the stack, and a pointer denoting the current "top" of the stack. II. What are the values of t1 and t2 after the code executes?

A set of instructions may be used to show a function's return address. Remember that any modifications you make to the stack cannot prevent the procedure from returning to its caller.
A sequence of instructions may be used to see the function's return address. Any modifications to the stack must be made with the return of the method to its caller in mind.
Complete the following ():a. A stack is used by the system when a function call is madeb. A stack can become full during program execution
3- Evaluate the following statement using stack : T= calculate (3) ; Where calculate () defined as follows : int calculate ( int n) { int x , y; if ( n<=1) return 1; else { x = calculate (n – 1) ; y = calculate ( n - 2 ); return x * y; } }
The code box below defines a variable route as a list of directions to navigate a maze. Each instruction is one of the following four basic commands: • higher. move one step in the positive y direction • lower: move one step in the negative y direction • left: move one step in the negative x direction right: move one step in the positive x direction ● Define a function move that takes two arguments, a location (as a tuple of x and y coordinates) and an instruction (higher, lower, left, right) as a string. Given the provided location, it should return the new location (as a tuple of x and y coordinates) when following the specified instruction. If the instruction is invalid, the old location should be returned. Use the function move to determine the final position when starting from the point (-2, -1) and following all instructions in the list route. Assign this final position to the variable final_location. Reset answer 1 route = ['right', 'higher', 'left', 'lower', 'higher', 'left',…
It is possible to see the function's return address by issuing a set of instructions. It's important to remember that modifying the stack shouldn't prevent the process from returning to its caller.
The return address of a function can be displayed via a series of commands. Keep in mind that any changes you make to the stack must not impede the return of the procedure to its caller
Evaluate the following statement using stack : t = power ( 2,3 ) ; Where power( ) defined as follows : int power ( int b , int h ) { int y ; if ( h == 0 ) return 1 ; else { y = power( b , h-1 ); return b*y ; } }
Evaluate the following statement using stack : Z = mod ( 10 , 3 ) ; Where mod ( ) defined as follows : int mod ( int x , int y ) { int m ; if ( x < y ) return x ; else { m = mod ( x - y , y ); return 0 + m ; } }
Given the code:10 void f1(int n) {11 cout << n;12 }13 int f2(int x) {14 f1(x);15 }1617 int main() {18 f1(5);19 f2(6);20 return 0;21 }1. Write the line number in the main function where the runtime stack is most complex.2. Create a simple diagram of the runtime stack for this program when it is the most complex. Clearly state what is top and bottom of the stack.
CPU Priority Scheduling-preemptive: Write a Java program to implement a priority scheduling algorithm that uses low number to represent high priority. Your program should first prompts the user to input a list of process ID, arrival time, burst time, and priority for each process to be run on the CPU. The list is terminated by 0 0 0 0 for the process ID, arrival time, burst time, and priority. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the Priority scheduling algorithm. Also print the turnaround time, response time, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.
Two stacks S1 and S2 can be implemented using one array. Write procedures: PopS1(Stack), PushS1(Stack,x), PopS2 (Stack), PushS2(Stack,x). The procedures should not declare an overflow unless every slot in the array is used.
