## --- Day 2: Corruption Checksum ---

As you walk through the door, a glowing humanoid shape yells in your direction. "You there! Your state appears to be idle. Come help us repair the corruption in this spreadsheet - if we take another millisecond, we'll have to display an hourglass cursor!"

The spreadsheet consists of rows of apparently-random numbers. To make sure the recovery process is on the right track, they need you to calculate the spreadsheet's *checksum*. For each row, determine the difference between the largest value and the smallest value; the checksum is the sum of all of these differences.

For example, given the following spreadsheet:

```
5 1 9 5
7 5 3
2 4 6 8
```

- The first row's largest and smallest values are
`9`

and`1`

, and their difference is`8`

. - The second row's largest and smallest values are
`7`

and`3`

, and their difference is`4`

. - The third row's difference is
`6`

.

In this example, the spreadsheet's checksum would be `8 + 4 + 6 = 18`

.

*What is the checksum* for the spreadsheet in your puzzle input?
