using Advent2020.Day1
input = readlines("inputs/day01.txt")
numbers = parse.(Int64, input)
# Part 1 solution
x, y = two_that_sum_to_total(2020, numbers)
println(x * y) # 388075
# Part 2 solution
x, y, z = three_that_sum_to_total(2020, numbers)
println(x * y * z) # 293450526See test/ for code snippets which produce solutions for the other days.
