# The K programming language

K is an APL-derived programming language which has more in common with line noise than with common code.

Example: Calculating the mean of a series of numbers:

```
X:1 2 3
(+/X)%#X
```

The first line defines a vector `X`

. The second line calculates the sum of all values (`+/`

) and divides (`%`

) it by the number of elements (`#`

).
