\--- 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?

Your puzzle answer was `45972`.

\--- Part Two ---
----------

"Great work; looks like we're on the right track after all. Here's a *star* for your effort." However, the program seems a little worried. Can programs *be* worried?

"Based on what we're seeing, it looks like all the User wanted is some information about the *evenly divisible values* in the spreadsheet. Unfortunately, none of us are equipped for that kind of calculation - most of us specialize in bitwise operations."

It sounds like the goal is to find the only two numbers in each row where one evenly divides the other - that is, where the result of the division operation is a whole number. They would like you to find those numbers on each line, divide them, and add up each line's result.

For example, given the following spreadsheet:

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

* In the first row, the only two numbers that evenly divide are `8` and `2`; the result of this division is `4`.
* In the second row, the two numbers are `9` and `3`; the result is `3`.
* In the third row, the result is `2`.

In this example, the sum of the results would be `4 + 3 + 2 = 9`.

What is the *sum of each row's result* in your puzzle input?

Your puzzle answer was `326`.
