PTA 乙级 1066 图像过滤 (15分) C++

 

 少一个for运行超时了???

 1 #include<iostream>
 2 #include<vector>
 3 
 4 using namespace std;
 5 
 6 int main() {
 7     int n = 0, m = 0;
 8     int a = 0, b = 0;
 9     int replace = 0;
10     cin >> m >> n >> a >> b >> replace;
11     int tmp = 0;
12     for (int i = 0; i < m; ++i) {
13         for (int j = 0; j < n; ++j) {
14             cin >> tmp;
15             if (j != 0)cout << ' ';
16             if (tmp >= a && tmp <= b) printf("%03d", replace);
17             else printf("%03d", tmp);
18         }
19         cout << endl;
20     }
21     return 0;
22 }

 

 神不神奇,意不意外

 1 #include<iostream>
 2 #include<vector>
 3 
 4 using namespace std;
 5 
 6 int main() {
 7     int n = 0, m = 0;
 8     int a = 0, b = 0;
 9     int replace = 0;
10     cin >> m >> n >> a >> b >> replace;
11     vector<vector<int>> px(m);
12     for (int i = 0; i < m; ++i) px[i].resize(n);        //创建二维数组
13     for (int i = 0; i < m; ++i)
14         for (int j = 0; j < n; ++j)
15             cin >> px[i][j];
16     for (int i = 0; i < m; ++i) {
17         for (int j = 0; j < n; ++j) {
18             if (j != 0)cout << ' ';
19             if (px[i][j] >= a && px[i][j] <= b) printf("%03d", replace);
20             else printf("%03d", px[i][j]);
21         }
22         cout << endl;
23     }
24 
25     return 0;
26 }
