Question

main 1. Trace the algorithm described by the flowchart below and determine the values of R1 and R2 in each loop at the conditional points (A and B in flowchart). Create a table like the one below listing these values through each loop until the program reaches 'exit'. Also, list the number of times the loop will execute and the final values of R1 and R2 when the program exits. R1 ? 3 R2 ? 0 R1 ? R1-1 loop 1 2 ... exit A: R1, R2 B: R1, R2 R2 ? R2+1 A R1 F ADD ?0? T B F R1 ? R1+3 R2 > 6? T ADD R2 ? R2+R1 return exit 2. The flowchart from Problem 1 includes two conditional tests and a subroutine. Create a new flowchart that defines how the program that executes this flowchart would be implemented within \"linear\" code, i.e. all actions must flow in a single line. Add wires (flow paths) as needed to achieve proper operation. You may assume the subroutine function will appear after the main loop exits.
