Write a program in Java, Python, or C/C++ that reads in a single character at a time, and when it reaches end-of-file, reports whether it has read in a decimal, octal, or hexadecimal number, and what that number is (as a string), or "NONSENSE" if it isn't a well-formed number. Name your program file lexical.{py|c|java} (suffix obviously depending on what language you choose).
