A friend asks you to tune into a local numbers station, a radio station that is publishing a coded message. They say they've had a tip on how to decipher the messages the station is publishing, but want your help in writing a program that will do the deciphering. You start listening to the station and notice that in each voice sample the person reads out a number follow by letter or a hyphen-. The numbers don't seem to be in any particular order... You decide that you're going to help write the program, so your friend shares what the tip was • Every sample will contain a number which can be used to put the messages in order (sequence ID). • Every message only contains the letters a-z. A complete message is a continuous set of characters surrounded by two characters. • Sometimes a message is never completed (missing sequence IDs). . Once you've completed a full message, all messages completed later with a lower sequence ID are no longer useful and shouldn't be output (you should only output the latest message). • If two full messages are completed at the same time, then you should output only the message containing higher sequence IDs. A full broadcast can contain multiple complete messages and you will need to output each of them. Function Description You are to implement the function Process Sample that takes: • a sequence number for the sample, • the character for the sample. Whenever a full message is completed you should call the OnMessage Complete function with the completed message. Constraints • 0 <sequence id <264-1. . • number of messages >= 1 Input Format For each line, the first string is the sequence number associated with the sample, the second character is the character related to the sequence number. Sample Case 0 Sample Input 1- 2 h 3 e 41 51 60 7- 8 b Sample Output hello Explanation When the samples are placed in order according to their sequence IDs we get the following, -hello-b. There is one complete message here (between the characters) so it is output. Sample Case 1 Sample Input 1- 2 b 3 y 5- 6 h ********* 71 8- 4 e Sample Output hi Explanation When the samples are placed in order according to their sequence IDs we get the following, -bye-hi-. This broadcast contains two complete messages (bye and hi), but because the second complete message (hi) was completed before the first (bye), we only output the later message (hi).
