JAVA（2021-11-13）leetcode每日一题----检测大写字母

简单的字符串模拟，写的有点麻烦了

class Solution {
    public boolean detectCapitalUse(String word) {
        if(word.length()<2){
            return true;
        }
        char[] words = word.toCharArray();
        //开头大写
        if(isBig(words[0])){
            if(isBig(words[1])){
                for(int i = 2;i=0 && c-'Z'<=0){
            return true;
        } else{
            return false;
        }
    }
}
