手动制表的你们累不累？
```
#include <iostream>
#include <string>
using namespace std;
int clicks[256] = { 0 };
void init_clicks()
{
const string keyboard[12] = {
"", "abc", "def",
"ghi", "jkl", "mno",
"pqrs", "tuv", "wxyz",
"*", " ", "#"};
for (int i = 0; i < 12; ++i)
for (int j = 0; j < keyboard[i].length(); ++j)
clicks[keyboard[i][j]] = j + 1;
}
int main()
{
init_clicks();
string s;
getline(cin, s);
int count = 0;
for (int i = 0; i < s.length(); ++i)
count += clicks[s[i]];
cout << count;
}
```
