Array change I

Problem

You are given an array $N$ containing exactly $20$ integers, indexed from $0$ through $19$.

Reverse the array by swapping symmetric pairs:

After all swaps, print the complete array in increasing index order. Each line must have exactly the form

N[i] = value

where i is the index and value is the value stored at that index after the reversal.

Input

The input contains exactly $20$ lines. Line $i+1$ contains integer $N[i]$ for $0\le i<20$.

Output

Print exactly $20$ lines. For every $0\le i<20$, print N[i] = value using the array value after reversal.

Subtasks

Subtask 1 (100 points): Exactly $20$ integers are given; $|N_i|\le 10^9$.

Example

Input

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20

Output

N[0] = 20
N[1] = 19
N[2] = 18
N[3] = 17
N[4] = 16
N[5] = 15
N[6] = 14
N[7] = 13
N[8] = 12
N[9] = 11
N[10] = 10
N[11] = 9
N[12] = 8
N[13] = 7
N[14] = 6
N[15] = 5
N[16] = 4
N[17] = 3
N[18] = 2
N[19] = 1

Explanation

After swapping $N[i]$ with $N[19-i]$ for $0\le i<10$, all 20 elements appear in reverse order.
