华为面试题（想完全通过测试太难了，搞了两个小时）
1、

public class Test{
    
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String str1 = scanner.nextLine();
        String str2 = scanner.nextLine();
        for (int i = 0;str1!=null && str2!=null && i < str2.length(); i++) {
            str1 = str1.replaceAll(String.valueOf(str2.charAt(i)), "");
        }
        System.out.println(str1);
        scanner.close();
    }
}

2、

public class Test2 {
    
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        while (true) {
            String inputString = scanner.nextLine();
            StringBuilder sb = new StringBuilder();
            if (inputString == null || "".equals(inputString) || inputString.length() > 100) {
                continue;
            }else {
                for (int i = inputString.length() - 1; i >= 0; i--) {
                    sb.append(inputString.charAt(i));
                }
                System.out.println(sb.toString());
                break;
            }
        }
        scanner.close();
    }
}
