In Swift, there are two types of comments:

1. Single-line comments start with //
2. Multi-line or inline comments start with /* and end with */

The input will be a sequence of //, /* and */. Every /* must have a */ that immediately follows it. In addition, there can be no single-line comments in between multi-line comments in between the /* and */.

Create a function that returns true if comments are properly formatted, and false otherwise.

Examples

commentsCorrect("//////") ➞ true
// 3 single-line comments: ["//", "//", "//"]

commentsCorrect("/**//**////**/") ➞ true
// 3 multi-line comments + 1 single-line comment:
// ["/*", "*/", "/*", "*/", "//", "/*", "*/"]

commentsCorrect("///*/**/") ➞ false
// The first /* is missing a */

commentsCorrect("/////") ➞ false
// The 5th / is single, not a double //
