360笔试 E卷2题代码+蹲一个第一题
输出n能拿27%
写完判断就剩9% 挺离谱的 有没有带哥知道错在哪了
1题 我日我懂了!!!! 我没判断空行 他有空行 但是不算合法的
#include <iostream>
#include<string>
#include <ctype.h>
using namespace std;
bool judge() {
string s;
getline(cin, s);
if (s.length() > 10)return false;
for(int i=0;i<s.length();++i){
if (!isalpha(s[i])) {
return false;
}
}
return true;
}
int main() {
int n;
cin >> n;
judge();
int ans = 0;
for (int i = 0; i < n; ++i) {
bool ansb = judge();
if (ansb)ans++;
}
cout << ans << endl;
return 0;
}
