# 2020 Day 1: Report Repair Copyright (c) Eric Wastl #### [Direct Link](https://adventofcode.com/2020/day/1) ## Part 1 Before you leave, the Elves in accounting just need you to fix your **expense report** (your puzzle input); apparently, something isn't quite adding up. Specifically, they need you to **find the two entries that sum to `2020`** and then multiply those two numbers together. For example, suppose your expense report contained the following: ``` 1721 979 366 299 675 1456 ``` In this list, the two entries that sum to `2020` are `1721` and `299`. Multiplying them together produces `1721 * 299 = 514579`, so the correct answer is **`514579`**. Of course, your expense report is much larger. **Find the two entries that sum to `2020`; what do you get if you multiply them together?** ## Part 2 The Elves in accounting are thankful for your help; one of them even offers you a starfish coin they had left over from a past vacation. They offer you a second one if you can find **three** numbers in your expense report that meet the same criteria. Using the above example again, the three entries that sum to `2020` are `979`, `366`, and `675`. Multiplying them together produces the answer, **`241861950`**. In your expense report, **what is the product of the three entries that sum to `2020`**?
