#include <stdio.h>

int main() {
    int row,column = 0;
    int i = 0;
    while (scanf("%d",&row) != EOF) {
        for (i = 1;i <= row; i++) {//整个图形要打印的行数
            for (column = 1; column <= row; column++) {
                if ((column == i) || column == row - (i - 1)) {
                    printf("*");
                }
                else {
                    printf(" ");
                }
            }
            printf("\n");    
    }
    }


    return 0;
}

对角线相等是解题关键
