In this assignment, you'll start getting familiar with xv6 by writing a couple simple programs that run in the xv6 OS.

For part 1 write a program for xv6 that, when run, prints "Hello world" to the xv6 console. This can be broken up into a few steps:

1. Create a file in the xv6 directory named hello.c

2. Code your program in hello.c such that it implements printing "Hello world"

3. Edit the file Makefile, find the section UPROGS which contains a list of programs to be built, and add a line to tell it to build your Hello World program. When you're done that portion of the Makefile should look like:

4. Run make to build xv6, including your new program (repeating steps 2 and 4 until you have compiling code)

5. Run make qemu to launch xv6, and then type hello in the QEMU window. You should see "Hello world" be printed out.

   Note: use the make clean command to clear the compiled files whenever necessary.

Please provide screenshots/commands/source code for the solution to the problem.
