计算整数110 (包括)的所有三个毕达哥拉斯方法

为这组正整数显示$ A(x_1,\ ldots,x_n)\ geq G(x_1,\ ldots,x_n)\ geq H(x_1,\ ldots,x_n)$

这三种方法中最常见的算术平均值是列表的总和除以其长度: $ A(x_1,\ ldots,x_n)= \ frac {x_1 + \ cdots + x_n} {n} $ 几何mean是列表产品的$ n $ th根: $ G(x_1,\ ldots,x_n)= \ sqrt [n] {x_1 \ cdots x_n} $ 调和平均值是$ n $除以总和列表中每个项目的倒数: $ H(x_1,\ ldots,x_n)= \ frac {n} {\ frac {1} {x_1} + \ cdots + \ frac {1} {x_n}} $

假设输入是包含所有数字的有序数组。

要获得答案,请按以下格式输出对象:

 {
  值:{
    算术:5.5,
    几何:4.528728688116765,
    谐波:3.414171521474055
  },
  测试:'是A> = G> = H?是'
}
## Instructions
## Tests
```yml tests: - text: pythagoreanMeans是一种功能。 testString: 'assert(typeof pythagoreanMeans === "function", "pythagoreanMeans is a function.");' - text: 'pythagoreanMeans([1, 2, ..., 10])应该等于上面相同的输出。' testString: 'assert.deepEqual(pythagoreanMeans(range1), answer1, "pythagoreanMeans([1, 2, ..., 10]) should equal the same output above.");' ```
## Challenge Seed
```js function pythagoreanMeans (rangeArr) { // Good luck! } ```
### After Test
```js console.info('after the test'); ```
## Solution
```js // solution required ```
