1.C语言版本

bool detectCapitalUse(char* word) {
    int cnt = 0;
    for(int i = 0; word[i]; i++)
        if(isupper(word[i]))
            cnt++;

    return cnt == 0 || cnt == strlen(word) || (isupper(word[0]) && cnt == 1); 
}

2.C++版本

class Solution {
public:
    bool detectCapitalUse(string word) {
        int cnt = ranges::count_if(word, ::isupper);
        return cnt == 0 || cnt == word.length() || cnt == 1 && isupper(word[0]);
    }
};
