Consider the following diagram representing seats in a movie theater where each seat is specified by a row number ranging from 1 to 7 (inclusive) and a column number ranging from 1 to 10 (inclusive). The theater's ticketing system has already allocated Andrew ("A"), Sally ("S") and Rufus ("R") seats for an upcoming screening.
The ticketing system stores ticketing information in a collection called TICKETS. TICKETS is composed of nodes where values alternate between integers and strings - each integer has encoded seating information for the customer whose name is held as a string in the next node. The first two digits and the last two digits of each integer specify the row number and column number of a seat respectively. For example, Rufus has a ticket for the third seat across in the second row. TICKETS contains only those customers with a ticket and all ticket holders have exactly one allocated seat each.
Write in pseudocode a procedure that outputs all ticket holder names held in TICKETS.
Identify one problem with storing ticketing information in this way and explain why a 2D array would be more appropriate.
Given a 12x10 2D array called TIX, write pseudocode to parse ticketing information from the collection TICKETS into TIX such that ticket holder names are copied to a TIX index representative of their seat location. For example, TIX, TIX, and TIX should hold the names "Andrew", "Rufas" and "Sally" respectively. Unassigned seats should be indicated in TIX by the string "Empty".
