// Find all comments in the Java (it could be Python or any other language of your choice) codes that’s parsed in as a string.
// You may assume the codes given is valid.

// Input is a single string, e.g.
// String codes =
// “/* file created by aonecode.com\\n” +
// “ welcome to the tech blog*/ \\n” +
// “//main method\\n” +
// “public static void main(String[] args) { \\n“ +
// “ System.out.println(“//welcome”); //output\\n” +
// “}”


// Output is a list of strings

// List<String> ret =
// [
// “ file created by anecode.com\n welcome to the tech blog”,
// “main method”,
// “output”
// ]
