Module day_2

This is my solution for Advent of Code - Day 2: Red-Nosed Reports

parse_input uses parse_report to turn the input file into Vec<Report>. first_bad_level_pair is used by both parts to find the first pair that causes the report to be unsafe. analyse_reports solves part 1. report_check_with_dampener applies the more relaxed check for part 2, trying the permutations of dropping a level that might allow the report to pass. analyse_reports_with_dampener uses that to get the part 2 solution.

Functions

• analyse_reports 🔒
  Solves part 1, counting all the reports that are safe as is
• analyse_reports_with_dampener 🔒
  Solves part 1, counting all the reports that are safe after dampening
• first_bad_level_pair 🔒
  Find the first pair in the report that either:
• parse_input 🔒
  Parse the input file into a list of reports
• parse_report 🔒
  Parse a line of input as a list of levels
• report_check_with_dampener 🔒
  If the report is unsafe, it can be considered safe enough if it becomes safe when removing one level.
• run
  The entry point for running the solutions with the ‘real’ puzzle input.
• without_index 🔒
  Returns a copy of the input report without the level at the specified index

Type Aliases

• Report 🔒
