Check Words Order - Facebok

LeetCode 953 - Verifying an Alien Dictionary
Input: Words = ['a', 'aa', 'cb', 'bc'] Order = ['a', 'c', ‘b']
Output: True
Input: Words = ['a', 'aa', 'cb', ‘bc'] Order = ['c', 'a', 'b']
Output: False (cb -> a -> aa -> bc)
意思就是给⼀一组words和⼀一个character的order list，请问words⾥里里⾯面是不不
是按照 order list⾥里里⾯面的order排序。 Return True or False

2. [“ab”, “a”] ⾮非范围内 的字⺟母？

    private boolean check(String wa, String wb, Map<Character, Integer> dict) {
        int len = Math.min(wa.length(), wb.length());
        for (int i = 0; i < len; i ++) {
            if (dict.get(wa.charAt(i)) < dict.get(wb.charAt(i))) return true;
            if (dict.get(wa.charAt(i)) > dict.get(wb.charAt(i))) return false;
        }
        if (wa.length() <= wb.length()) return true;
        else return false;
    }

    private boolean checkOrder(String[] words, char[] diction) {
        HashMap<Character, Integer> dict = new HashMap<Character, Integer>();
        for (int i = 0; i < diction.length; i ++)
            dict.put(diction[i], i);
        
        for (int i = 0; i < words.length - 1; i ++)
            if (!check(words[i], words[i + 1], dict))
                return false;
        return true;
    }

- not exist words
