模拟题 是一道练STL的好题
AC代码:
1 #include<bits/stdc++.h> 2 using namespace std; 3 typedef long long ll; 4 typedef unsigned long long ull; 5 6 namespace io { 7 const int SIZE = 1e7 + 10; 8 char inbuff[SIZE]; 9 char *l, *r; 10 inline void init() { 11 l = inbuff; 12 r = inbuff + fread(inbuff, 1, SIZE, stdin); 13 } 14 inline char gc() { 15 if (l == r) init(); 16 return (l != r) ? *(l++) : EOF; 17 } 18 void read(int &x) { 19 x = 0; char ch = gc(); 20 while(!isdigit(ch)) ch = gc(); 21 while(isdigit(ch)) x = x * 10 + ch - ‘0‘, ch = gc(); 22 } 23 } using io::read; 24 25 int main(){ 26 int np; 27 cin>>np; 28 string s[13]; 29 map <string, int> get; 30 map <string, int> out; 31 string name; 32 string name0; 33 int n, m; 34 for (int i = 1; i <= np; i++) cin>>s[i]; 35 for (int i = 1; i <= np; i++){ 36 cin>>name; 37 cin>>n>>m; 38 if (m){ 39 out[name] += (n / m) * m; 40 for (int j = 1; j <= m; j++){ 41 cin>>name0; 42 get[name0] += n / m; 43 } 44 } 45 } 46 for (int i = 1; i <= np; i++) 47 cout<<s[i]<<‘ ‘<<get[s[i]] - out[s[i]]<<endl; 48 return 0; 49 }
