这道题除了小写字母还有别的字符吗 为什么读入这样写前5个点TLE

void init() {
	char c;
	s[0] = 'z' + 1, s[++n] = '*';
	while((c = getchar()) != '\n' && c != '\r') s[++n] = c, s[++n] = '*';
	return;
}

这样写就A了

void init() {
	char c;
	s[0] = 'z' + 1, s[++n] = '*';
	while((c = getchar()) >= 'a' && c <= 'z') s[++n] = c, s[++n] = '*';
	return;
}
