Xiaoming wants to play chess, but he doesn't have a chessboard. Therefore, he wants to record the coordinates and then present them as an image. Please write a program to help Xiaoming solve this problem.
The chessboard is 10x10 in size.
Sample Inputs/Outputs
| Sample Input(s) | Sample Output(s) |
|---|---|
| The input consists of N lines, terminated by EOF.
Format: (y value, x value) y value represents the row number (vertical), and x value represents the column number (horizontal). | The output consists of ten lines, as shown in the example output. The numbers in the chessboard represent the steps. |
| (1,5) (6,7) (10,10) (8,4) (7,9) | —-1—– ———- ———- ———- ———- ——2— ——–5- —4—— ———- ———3 |
| (1,1) (3,7) (2,8) | 1——— ——-3– ——2— ———- ———- ———- ———- ———- ———- ———- |
Thought Process
After extracting the coordinates, use a Map to record the position of each coordinate. Then, iterate through a loop of 10x10. If the current (i, j) is stored in the Map and not equal to 0, output this Map value; otherwise, output '-'.
Sample Code－ZeroJudge L003: Chessboard
#include <iostream>
#include <map>
using namespace std;
pair<int, int> axis (int a, int b)
{
pair<int, int>tmp;
tmp.first = a;
tmp.second = b;
return tmp;
}
int main() {
cin.sync_with_stdio(0);
cin.tie(0);
string str;
int count = 1;
map<pair<int, int>, int>MAP;
while (cin >> str)
{
int a, b;
if (str[2] != ',')
{
a = 10;
if (str[5] != ')') b = 10;
else b = int(str[4] - '0');
}
else
{
a = int(str[1] - '0');
if (str[4] != ')') b = 10;
else b = int(str[3] - '0');
}
MAP[axis(a, b)] = count;
count++;
}
for (int i = 1; i<=10; i++)
{
for (int j = 1; j<=10; j++)
{
if (MAP[axis(i, j)] != 0) cout << MAP[axis(i, j)];
else cout << "-";
}
cout << "\n";
}
