It's almost as if it's running a syscall with the input number as a code, which would explain why the first four numbers output things (the first four syscalls output data). My code currently is producing wrong output and I cannot identify which part should be edited. The "classic" Fibonacci sequence, if there can be said to be such a thing, is the sequence where a 0 = 1 and a 1 = 1. Edit Execute 1 # Compute firs O Select the Edit tab in the upper right to return to the program editor. It does make sense, Thanks!
