To celebrate the upcoming CCC (Canadian Computing Contest), Max decided to define a new sorting algorithm called *Bob Sort*.

Bob Sort involves rounds of sorting.

For the round, Bob Sort looks at the rightmost digits, :

If there are fewer than digits in element , the left-aligned missing digits are set to .

Then, Bob Sort sorts the elements by their corresponding value in non-decreasing order.

Can you Bob Sort the array into increasing order?

#### Constraints

All are distinct.

#### Input Specification

The first line will contain , the number of elements in the array.

The next line will contain space-separated integers, the elements of the array.

#### Output Specification

Output lines, the array after each round of sorting.

**Note: Within a round, ties do not need to be broken between elements with the same value, .**

#### Sample Input 1

```
6
2 105 12 1 15 65
```

#### Sample Output 1

```
1 2 12 105 15 65
1 2 105 12 15 65
1 2 12 15 65 105
```

#### Sample Input 2

```
1
100
```

#### Sample Output 2

```
100
100
100
```

Stupid problem. Gives wrong answer for printing extra space after line.
