用C++STL写好容易超时啊C++STL写思路蛮自然也方便……就是超时得厉害
郁闷……
#include <iostream>
#include <vector>
#include <map>
using namespace std;
void delcon(string &str)
{
int index = 0;
while(index < str.length())
{
if(str[index] == '-')
{
str.erase(index,1);
continue;
}
++index;
}
}
void pout_book(map<string, int> telbook)
{
map<string, int>::iterator bookIter = telbook.begin();
for(;bookIter != telbook.end(); ++bookIter)
{
string tempStr = bookIter->first;
if(bookIter->second>1)
{
tempStr.insert(3,"-");
cout<<tempStr<<" "<<bookIter->second<<endl;
}
}
}
void trance(string &str)
{
for(int index=0; index < str.length(); ++index)
{
switch(str[index]){
case 'A':case 'B':case 'C':
(str[index]) = '2';break;
case 'D':case 'E':case 'F':
(str[index]) = '3';break;
case 'G':case 'H':case 'I':
(str[index]) = '4';break;
case 'J':case 'K':case 'L':
(str[index]) = '5';break;
case 'M':case 'N':case 'O':
(str[index]) = '6';break;
case 'P':case 'R':case 'S':
(str[index]) = '7';break;
case 'T':case 'U':case 'V':
(str[index]) = '8';break;
case 'W':case 'X':case 'Y':
(str[index]) = '9';break;
default:break;
}
}
}
int main()
{
int turns = 0;
map<string,int> telBook;
cin>>turns;
for(;turns > 0; --turns)
{
string curStr("");
cin>>curStr;
delcon(curStr);
trance(curStr);
++telBook[curStr];
}
pout_book(telBook);
}
