```c
#include <stdio.h>
int main()
{
int n;
scanf("%d", &n);
for (int i = 0; i < n; i++) {
for (int j = 1; j <= n; j++) {
int a = i * n + j;
if (a < 10) {
printf("%d", 0);
}printf("%d", a);
}printf("\n");
}
printf("\n");
int count = 0;
for (int i = 1; i <= n; i++) {
for (int k = n - i; k > 0; k--)printf(" ");//这里应该是n - i
for (int j = 1; j <= i; j++) {
count++;
if (count < 10) {
printf("%d", 0);
}printf("%d", count);
}
printf("\n");
}
return 0;
}
```
总边长是n 不是4

其实还有一种解决方法，不用专门输出前导0
可以用 `printf("%.2d")`直接就可以输出两位整数（不足两位会有0补位的）

@[co7ahang](/user/831011) 是printf("%02d")，不是printf("%.2d")
