codeforces#P1950A. Stair, Peak, or Neither?
Stair, Peak, or Neither?
Description
You are given three digits $a$, $b$, and $c$. Determine whether they form a stair, a peak, or neither.
- A stair satisfies the condition $a<b<c$.
- A peak satisfies the condition $a<b>c$.
The first line contains a single integer $t$ ($1 \leq t \leq 1000$) — the number of test cases.
The only line of each test case contains three digits $a$, $b$, $c$ ($0 \leq a$, $b$, $c \leq 9$).
For each test case, output "STAIR" if the digits form a stair, "PEAK" if the digits form a peak, and "NONE" otherwise (output the strings without quotes).
