help me please :(

You are building a Music Player app. You need to implement the MusicPlayer class, which should hold the track names as Strings in an array. The array is already defined in the given code. The player should support the following functions: add: add the given argument track to the tracks array. show: output all track names in the player on separate lines. play: start playing the first track by outputting "Playing name" where name is the first track name. You can add a new item to an array using +=, for example: tracks += track https://code.sololearn.com/cQg7CVOttYj5/?ref=app

|[CNC]| ArCH. ExoTesla , there are 2 issues in the code: ▪︎function add() in class MusicPlayer needs to be reworked (2 items) ▪︎main function was modified (may be by accident) AND: ▪︎the complete code has a real bad formatting, that makes it difficult to read and to maintain. here is the code reworked at the marked lines (//****) that should run properly : https://code.sololearn.com/ctVT1EPrGczk/?ref=app

|[CNC]| ArCH. ExoTesla , you have already done around 90 % of the kotlin tutorial and you also have completed various other language tutorials, so i don't think that you are a newbie. please be realistic. having this in mind, i am sure you can solve this exercise. take some time and effort, and do a try by yourself. if you get stuck, come back, show us your code and you will get help from the community. happy coding!
