如何求最大值和最小值

求最大值和最小值的方法取决于你处理的数据类型和上下文。以下是一些常见情况下的求解方法：

数组或列表

1. Python:

```python

numbers = [1, 3, 5, 7, 9]

max_value = max(numbers)

min_value = min(numbers)

```

2. JavaScript:

```javascript

let numbers = [1, 3, 5, 7, 9];

let max_value = Math.max(...numbers);

let min_value = Math.min(...numbers);

```

多维数组或列表

1. Python:

```python

numbers = [[1, 3, 5], [7, 9, 11], [13, 15, 17]]

max_value = max(map(max, numbers))

min_value = min(map(min, numbers))

```

集合（Set）

1. Python:

```python

numbers = {1, 3, 5, 7, 9
