+Now that you've identified which tickets contain invalid values, [1m[37mdiscard those tickets
+entirely[0m. Use the remaining valid tickets to determine which field is which.
+
+Using the valid ranges for each field, determine what order the fields appear on the tickets. The
+order is consistent between all tickets: if seat is the third field, it is the third field on every
+ticket, including [1m[37myour ticket[0m.
+
+For example, suppose you have the following notes:
+
+class: 0-1 or 4-19
+row: 0-5 or 8-19
+seat: 0-13 or 16-19
+
+your ticket:
+11,12,13
+
+nearby tickets:
+3,9,18
+15,1,5
+5,14,9
+
+Based on the [1m[37mnearby tickets[0m in the above example, the first position must be row, the
+second position must be class, and the third position must be seat; you can conclude that in
+[1m[37myour ticket[0m, class is 12, row is 11, and seat is 13.
+
+Once you work out which field is which, look for the six fields on [1m[37myour ticket[0m that
+start with the word departure. [1m[37mWhat do you get if you multiply those six values
+together?[0m
