b$)$ It is assumed that $5$ and $3$ are already in registers $R1$ and $R2,$ respectively. Perform

subtraction $5-3$ and store the result in Register R$3.$

Based on the above problem statement, answer the following four questions, using

the $1C-3$ computer's ISA.

a$)$ Using structured programming technique, create a flowchart that solves the

problem statement by using sequential, conditional, and iterative constructs.

b$)$ Which instruction$($s$)$ from the LC$-3$ ISA will be used for executing each of the steps

in the flowchart?

c$)$ Using the identified instructions, translate the flowchart into an LC$-3$ assembly

language program that solves the problem statement.

d$)$ Translate the $LC-3$ assembly language program into an $LC-3$ machine language

program.
