2828. 判别首字母缩略词

C代码1：

bool isAcronym(char ** words, int wordsSize, char * s){
    if (wordsSize != strlen(s)) {
        return false;
    } 
    for (int i = 0; i < wordsSize; ++i) {  // 遍历所有，没有不满足的就是满足的
        if (words[i][0] != s[i]) {
            return false;
        }
    }
    return true;
}

C代码2：

bool isAcronym(char ** words, int wordsSize, char * s){
    char* str = (char*)malloc(sizeof(char) * 101);
    int strTop = 0;
    for (int i = 0; i < wordsSize; ++i) {
        str[strTop++] = words[i][0];
    }
    str[strTop] = '\0';
    return strcmp(str, s) == 0;
}
