### A good answer might be:

`0000 1111 1010 0101` |  |  | `0FA5`
`0011 0110 1000 1111` |  |  | `368F`
`---- ---- ---- ----` |  |  | `----`
`0011 1001 0010 1010` |  |  | `392A`

# Example Program

Here is a program that does all three bitwise operations between the same two patterns. The register is different in each case.

    ## Program to bitwise OR, AND, and XOR two patterns
            .text
            .globl  main

    main:
            ori     $15, $0,0x0FA5       # put bit pattern register into $15
            ori      $8,$15,0x368F       # OR with second pattern
            andi     $9,$15,0x368F       # AND with second pattern
            xori    $10,$15,0x368F       # XOR with second pattern

Running it in SPIM (pushing F10 four times) results in the following:

### QUESTION 13:

What is the exclusive-OR of a bit pattern with itself? Try this with a few bit patterns written on a scrap of paper.
