Problem Statement

Calculate how much it would cost to ship a box given its weight and dimensions. The shipping service charges rate dollars for each pound that a package weighs. However, if a package weighs less than thresholdWeight pounds and its (length + girth) is greater than thresholdSize inches, it is billed as a package that weighs thresholdWeight pounds. The length of a box is its longest side. The girth is the distance around the box perpendicular to the length. In other words, if the two non-length sides are called width and height, girth is defined as width + height + width + height. If a box has two equal sides that are greater than the third side, or if a box has three equal sides, any of the multiple longest sides can be used as the length.

The dimensions of the box are given as a String formatted as "<side>x<side>x<side>" (quotes for clarity only), where each <side> is a positive integer with no leading zeros. All lengths are given in inches, and all weights are given in pounds.

Definition

Class:: ShippingCost
Method:: getCost
Parameters:: String, int, int, int, int
Returns:: int
Method signature:: int getCost(String dimensions, int weight, int rate, int thresholdSize, int thresholdWeight)
(be sure your method is public)

Constraints

dimensions will be formatted as "<side>x<side>x<side>" (quotes for clarity only), where each <side> is an integer between 1 and 100, inclusive, with no leading zeros. Each 'x' is lowercase.
weight will be between 1 and 100, inclusive.
rate will be between 1 and 10, inclusive.
thresholdSize will be between 20 and 300, inclusive.
thresholdWeight will be between 30 and 100, inclusive.

Examples

```
"10x4x5"
```
```
50
```
```
2
```
```
25
```
```
75
```
```
Returns: 150
```
The length of this box is 10 and the girth is 4 + 5 + 4 + 5 = 18. Since (length + girth) = 28, which is greater than thresholdSize, and the box weighs less than thresholdWeight pounds, it is treated as a package that weighs thresholdWeight pounds. The shipping cost is therefore 75 * 2 = 150.
```
"5x4x10"
```
```
50
```
```
2
```
```
28
```
```
75
```
```
Returns: 100
```
The (length + girth) of this box is exactly equal to thresholdSize, so the cost is simply 50 * 2 = 100.
```
"100x100x100"
```
```
99
```
```
10
```
```
300
```
```
100
```
```
Returns: 1000
```
The (length + girth) of this box is 500, which is greater than thresholdSize, and its weight is less than thresholdWeight. The shipping cost is therefore 100 * 10 = 1000.
```
"100x100x100"
```
```
100
```
```
10
```
```
30
```
```
70
```
```
Returns: 1000
```
