b$)$ It is assumed that $5$ and $3$ are already in registers R$1$ and R$2\_\{1\}$ 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 LC$-3$ 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.
