There have been many "Do __ without __" challenges before, but I hope that this is one of the most challenging.
You are to write a program that takes two natural numbers (whole numbers > 0) from STDIN, and prints the sum of the two numbers to STDOUT. The challenge is that you must use as few
- signs as possible. You are not allowed to use any sum-like or negation functions.
If two programs have the same number of
- characters, the winner is the person with fewer
Not Allowed: Languages in which the standard addition/subtraction and increment/decrement operators are symbols other than
- are not allowed. This means that Whitespace the language is not allowed.
