This month’s challenge is dedicated to the memory of Frances Allen, who passed away in August. Among her many accomplishments is the invention of the control-flow graph, in her 1970 paper “Control flow analysis“
with step number: 10 A = a 20 B = b 30 JMP_ZERO B 90 40 AA = A 50 BB = B 60 A = B 70 B = AA % BB 80 JMP 30 90 RETURN A ----- without step number: A = a B = b JMP_ZERO B 90 AA = A BB = B A = B B = AA % BB JMP 30 RETURN A
IBM Gadi submission result:
Thanks! This indeed computes the GCD, but the requirement on the number of paths is not fulfilled.
