WebWrite the LC-3 code to subtract the value in R1 from the value in R0 and place the result in R5. That is, write the assembly code for R5 := R0 - R1. Problem 2 Write the LC-3 assembly code to determine the maximum of two values. The two input values are in R0 and R1, and the code should place the greater of these two numbers into register R5. WebA neat trick in LC3 to copy the value of one register directly to another: ADD R5, R6, #0; R5 ← (R6) + 0, i.e. R5 ← (R6) If the result is negative, remember that you will have to print two characters, not one (there is no ASCII code for ‘-1’, right?) If you are struggling with writing LC3 code from scratch, try writing the program out in pseudo-code or even C++ first.
