permutation-parity
|
||
|
|
==================
|
||
|
|
Computes the [parity of a permutation](http://en.wikipedia.org/wiki/Parity_of_a_permutation).
|
||
|
|
|
||
|
|
# Example
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var sgn = require("permutation-parity")
|
||
|
|
|
||
|
|
console.log(sgn([0, 1, 2]), sgn([0, 2, 1]))
|
||
|
|
```
|
||
|
|
|
||
|
|
# Install
|
||
|
|
|
||
|
|
```
|
||
|
|
npm install permutation-parity
|
||
|
|
```
|
||
|
|
|
||
|
|
# API
|
||
|
|
|
||
|
|
#### `require("permutation-parity")(p)`
|
||
|
|
Determines the sign of a permutation
|
||
|
|
|
||
|
|
* `p` is a permutation
|
||
|
|
|
||
|
|
**Returns** The sign of the permutation:
|
||
|
|
|
||
|
|
* `1` if `p` is odd
|
||
|
|
* `-1` if `p` is even
|
||
|
|
* `0` if `p` is not a permutation
