Q1. a) The Little Man Computer (LMC) is an instructional model of a computer used to teach students all of the basic features of a modern computer in a simplified way. The following Little Man program is supposed to add two input numbers and output the result, i.e.,   OUT = IN1 + IN2 Mailbox Mnemonic code Numeric code 00 IN 901 01 STO 99 399 02 IN 901 03 ADD 99 199 04 OUT 902 05 COB 000     i) Change the program above to add the numbers 157 and 13. (Hint: these numbers are constants and therefore can pre-exist into memory before the execution of the program). No need to write both mnemonics and numeric codes (opcodes), either one is fine. Please refer to the instruction set provided for all the LMC instruction mnemonics and opcodes.
