# PROBLEM:

Given the seat numbering plan of a bus and specific seat in it, output whether the set is in the upper or lower deck, and a single or double seat.

# EXPLANATION:

Looking at the seat plan, we can see that for seat number N:

- If 1 \leq N \leq 10, the seat is Lower Double
- If 11 \leq N \leq 15, the set is Lower Single
- If 16 \leq N \leq 25, the seat is Upper Double
- If 26 \leq N \leq 30, the seat is Upper Single

Check which one of the four conditions N satisfies, and output the appropriate type.

# TIME COMPLEXITY

\mathcal{O}(1) per test case.

# CODE:

## Editorialist's code (Python)

```
for test in range(int(input())):
n = int(input())
if n <= 10: print('Lower Double')
elif n <= 15: print('Lower Single')
elif n <= 25: print('Upper Double')
else: print('Upper Single')
```
