That number does exists in Roman. The only that can be represented with more than 3 repetitions is M, 1000.This comment has been minimized.Copy link Quote reply.rockcesar commented Feb 11, 2018.Watch my Roman conversion to arabic. It does use many if:This comment has been minimized.Copy link Quote reply.Willem3141 commented Dec 29, 2018.Random note: this chokes on invalid numbers like IC (returns 101 instead of expected 99 ). Assuming we actually want to reject this input, this can easily be fixed by checking afterwards if the Arabic number, if converted back to Roman, yields the input again.© 2019 GitHub, Inc.
