Create a function called repeatNote, that takes as parameters a note as string and a number n.
The function returns a string where the given note is repeated n numbers of times, each time separated by a white space, without white space at the end.
For example calling repeatNote("C#", 3) should return "C# C# C#".
There are a number of ways to achieve this, for example by using the following methods: MDN string.repeat() and MDN string.trim()
