# CodeChef : December Challenge 2016 – Train Partner

By | December 6, 2016
##### Train Partner

Rahul and Rashi are off to the wedding of a close relative. This time they have to travel without their guardians (Train Partner). Rahul got very interested in the arrangement of seats inside the train coach.

The entire coach could be viewed as an arrangement of consecutive blocks of size 8.

``````
Berth Number   	Compartment

1 -  8               1
9 - 16               2
17 - 24               3
... and so on
``````

Each of these size-8 blocks are further arranged as:

``````
1LB,  2MB,  3UB,  4LB,  5MB,  6UB,  7SL,  8SU
9LB, 10MB, ...
...
...
``````

Here `LB` denotes lower berth, `MB` middle berth and `UB` upper berth.

The following berths are called Train-Partners:

``````
3UB   |  6UB
2MB   |  5MB
1LB   |  4LB
7SL   |  8SU
``````

and the pattern is repeated for every set of 8 berths.

Rahul and Rashi are playing this game of finding the train partner of each berth. Can you write a program to do the same?

### Input

The first line of input contains a single integer T, denoting the number of test cases to follow.

The next each T lines contain a single integer N, the berth number whose neighbor is to be found out.

### Output

The output should contain exactly T lines each containing the berth of the neighbor of the corresponding seat.

• 1T8
• 1N8

• 1T100
• 1N500

### Example

```Input:
