Given an integer array, find three numbers whose product is maximum and output the maximum product.

Example 1:

```Input: [1,2,3]
Output: 6
```

Example 2:

```Input: [1,2,3,4]
Output: 24
```

Note:

1. The length of the given array will be in range [3,104] and all elements are in the range [-1000, 1000].
2. Multiplication of any three numbers in the input won't exceed the range of 32-bit signed integer.

```class Solution {
public int maximumProduct(int[] nums) {
Arrays.sort(nums);

int s1 = nums[0] * nums[1] * nums[nums.length-1];
int s2 = nums[0] * nums[nums.length-1] * nums[nums.length-2];
int s3 = nums[nums.length-1] * nums[nums.length-2] * nums[nums.length-3];

return Math.max(Math.max(s1, s2), s3);
}
}```
