You are asked to simulate a music player. The music player is initialized with time =0min and one default song = "Greensleeves" with duration 5min. This song can never be removed from the music player. The player will play all songs in the list order and repeat again and again. There are 5 operations available for the music player. In this problem, you can also assume the operation is sorted by the time. Your program should read the input from the file, and output the answer to another file. The first argument is the input file name, while the second argument is the output file name. Name your program as "lab1-q4.c". Input file: Each line contains one operation in the table above. You can assume that the name of the song contains capital or small letters only. The length of a song will not be longer than 100. Output file: Output the results based on the query and print operations. You can assume the maximum number of songs in the playlist does not exceed 100. Sample Input: Add BadRomance 45 Query 5 Insert Greensleeves HA 120 Query 20 Print 21 Delete BadRomance 40 Query 42 Print 42 Query 43 Print 43 Sample Output: Greensleeves BadRomance Greensleeves HA BadRomance BadRomance Greensleeves HA BadRomance Greensleeves Greensleeves HA Note: If you have a trailing space at the end of line, you will receive "wrong answer". Take this sample output as an example, if it is written in a string, it will be, "Greensleeves BadRomance GreensleevesHA BadRomance BadRomance GreensleevesHA BadRomance Greensleeves \ ngreensleeves HA " You are asked to simulate a music player.
