#J, <s>15</s> 7 chars, 1 tie breaker, incomplete program This is my J attempt. It is not a full program, because I have not yet figured out how to write one. Just put that line in a script to get the function `p` that can be used for adding an arbitrary amount of numbers. It is a monad and takes a list of numbers to add (such as `p 1 2 3 4`): p=:#@#~ The idea is very simple. The function is written in tacit aka pointless style. Here is a pointed definition: p=:3 :'##~y' Read from right to left. In the tacit version, `@` composes the parts of the function. (like a ∘ in mathematics [(f∘g)(x) = f(g(x)]) * `y` is the parameter of `p`. * `~` makes a verb reflexive. For some verb `m`, `m~ a` is equal to `a m a`. * `#` (copy, `a#b`): Each element in `a` is replicated `i` times, where `i` is the element at the same index as the current element of `a` of `b`. Thus, `#~` replicates an item `n` `n` times. * `#` (count, `#b`): Counts the number of elements in `b`. Conclusion: J is awsome and less readable than Perl (that makes it even more awsome) ##Edits * 15 -> 7 using `#` instead of `i.`. Yeah! Less chars than golfscript. ##More of a program This one queries for input, but it still isn't a full program: (13 chars, 3 breakers) ##~".1!:1<#a:
