找规律罢了

解题思路:找规律~~

注意事项:

参考代码:

#include

using namespace std;

int main() {

int a;

cin >> a;

int n = 1;

int s[a][a] = {0};

for (int j = 0; j < a; j++)

s[0][j] = (j + 1) * (j + 2) / 2;

for (int i = 1; i < a; i++) {

for (int j = 0; j < a - i; j++) {

s[i][j] = s[0][j + i] - i;

}

}

for (int i = 0; i < a; i++) {

for (int j = 0; j < a - i; j++) {

if (j < a - i - 1)

cout << s[i][j] << " ";

else

cout << s[i][j];

}

cout << endl;

}

return 0;

}
