Scope of the task

Implement a feature that removes the comments from a TypeScript code using the following interfaces.

interface ICodeCommentRemover { 
 trimComment(c: string): void; 
}

interface ICodeWriter { 
 write(c: string): void; 
}

The method trimComment receives the TypeScript code char by char. The interface ICodeWriter may have several implementations for different outputs (text file, console). This implementation is not in the scope of your task.

Scenario

Input:

// some comments 
var result = a / b; 

Output:

var result = a / b;
