Letters and characters can be represented as 8-bit binary ASCII code values. For example 'A' is represented by the hex string 0x41 while 'a' is represented by the hex string 0x61. The C code below checks whether an ASCII character is an upper-case letter and then adds 0x20 to make it a lower-case letter. Translate the C code below to MIPS assembly. The ASCII character is stored in register $4. You may use registers $5-$25 as temporary registers and you may use $0 for the value 0. Do your best to follow the MIPS style guidelines.
