Calorie Counting

Sums groups of numbers separated by blank lines into an vec sorted in ascending order.

Since we don’t care what order the highest values are returned in select_nth_unstable would also work, and in theory is a little faster, however the difference was negligible when benchmarking.

Functions

• parse
  Parse and group lines.
• part1
  Use a reverse iterator to find the elf with the most calories.
• part2
  Use a reverse iterator to sum the calories of the 3 highest elves.
