## Question
托斯跟德瑞克大戰時，為了應對德瑞克的染色體斬擊，托斯也抽出了一條染色體出來應戰，然而此舉卻對他造成了不可挽回的傷害。托斯在接受治療後積極復健，今天復健師要托斯背出乘法表，但托斯卻怎麼也背不起來，可以請你給托斯一點提示嗎？

### Input
輸入一個整數N

### Output
輸出請依範例輸出NN乘法表
最後請記得輸出'\n'

### Constraint
1 <= N <= 9

### Sample Input

5

9

### Sample Output

1 * 1 =  1 | 2 * 1 =  2 | 3 * 1 =  3 | 4 * 1 =  4 | 5 * 1 =  5
1 * 2 =  2 | 2 * 2 =  4 | 3 * 2 =  6 | 4 * 2 =  8 | 5 * 2 = 10

## 作法
雙重迴圈

## 常見問題
- scanf 記得取址
- 注意最後一行後面緊接換行，不要輸出空格

## 解法

#include <stdio.h>

int main() {
    int n;
    scanf("%d", &n);
    for (int i = 1; i <= n; i++) {
        for (int j = 1; j <= n; j++) {
            printf("%d * %d = %2d", j, i, i * j);
            printf(j == n ? "\n" : " | ");
        }
    }
}
