Given the text file citytpr.txt containing temperature readings for various cities, develop a Raptor algorithm to sort the temperatures in decreasing values. The sorted temperatures shall be written to a file called sortedcitytpr.txt. The content of the files citytpr.txt and sortedcitytpr.txt must be stored in the formats shown below. For each city, the citytpr.txt includes the city name and the temperature respectively. The solution must work for any arbitrarily large file ( i.e. the number of city-temperature records must not be hard coded in the algorithm).

Since it is a sorting problem, the solution must resemble something like the main chart for the insert, selection or the bubble sorting algorithm - anyone of these will do. The only differences may be : (1) the sorting order (increasing or decreasing), (2) the swap. F

The submission must be an executable Raptor file of your flowchart solution. Any other forms of submissions will be marked as zero.
