新浪一道面试题：写一个函数，算出两个文件的相对路径的 递归算法

 

   public static void main(String[] args) throws Exception {

        String pathA = "/a/b/c/d/g/m/1.txt";

        String pathB = "/c/b/c/d/g/h/2.txt";         System.out.println(pathARelativePathBRecursion(pathA,pathB,""));     }

    /**

     * pathA相对于pathB的相对路径 递归算法:      *      * @param pathA      * @param pathB      * @param i      * @return      */     public static String pathARelativePathBRecursion(String pathA,String pathB, String tempPath) {         if (pathA.startsWith(pathB))             return pathA.replaceFirst(pathB+"/",tempPath.substring(0,tempPath.length()-3));         else             return pathARelativePathBRecursion(pathA, pathB.substring(0, pathB.lastIndexOf("/")), "../" + tempPath);     }
