题目大意:
给你几个人的名字和他们的生日,求生日相同的人的生日和他们的名字。
正文:
对于每个生日开一个 \(\texttt{vector}\),我开到了 \(\texttt{1231}\),如果足够聪明可能可以只开到 \(\texttt{366}\)。
代码:
inline ll READ()
{
ll x = 0, f = 1;
char c = getchar();
while (c != '-' && (c < '0' || c > '9')) c = getchar();
if (c == '-') f = -f, c = getchar();
while (c >= '0' && c <= '9') x = (x << 3) + (x << 1) + c - '0', c = getchar();
return x * f;
}
int n;
bool flag = 1;
vector <string> a[1300];
bool cmp(string a, string b)
{
int as = a.size(), bs = b.size();
if (as == bs) return a < b;
return as < bs;
}
int main()
{
n = READ();
for (int i = 1; i <= n; i++)
{
string s; int x;
cin >> s;
x = READ() * 100 + READ();
if (!a[x].empty()) flag = 0;
a[x].push_back(s);
}
if (flag) {puts("None"); return 0;}
for (int i = 101; i <= 1231; i++)
if (!a[i].empty())
{
printf ("%d %d ", i / 100, i % 100);
sort (a[i].begin(), a[i].end(), cmp);
for (int j = 0; j < a[i].size(); j++)
cout << a[i][j] << ' ';
putchar(10);
}
return 0;
}
