PUSH $,$ tos $++$ Your program will find the sum of the numbers input and display all the input values. You will write an assembly language project $($using the virtual machine described in class and available on Canvas$)$ to perform four tasks. These tasks will build on each other, starting with the most straightforward program and progressing to the complete program. The comprehensive program will read in numbers from the keyboard until the value $-1$ is entered, then display all the numbers described in tasks.

Task $1$: This program should read in numbers until $-1$ is entered, then display the sum of all single$-$digit numbers $[-9,-2]$ and $[0,9]$ entered. $-1$ is a flag to end the program; do not use $-1$ in the sum. Call this program $$task$1.$asm$.[10$ Points$]$

Task $2$: This program should read in numbers until $-1$ is entered. If the entered number lies between $100$ and $999,$ check whether the entered number is a prime number. If yes, find the sum of all prime numbers and display the sum. Call this program $$task$2.$asm.$[15$ Points$]$

Task $3$: This final version should read in numbers until $-1$ is entered. It should display all of the numbers entered, followed by printing out the total of these numbers following these rules: Call this program $$task$3.$asm.$[25$ Points$]$

If the total number is a single$-$digit number, compute the cube of the number. $[10$ Points$]$

If the total number is greater than or equal to ten, then compute the square of a number. $[10$ Points$]$

Do not display $-1$ as being entered, nor include it in the total. $[5$ Points$]$
