Reading Consistency Checker

You are given data for multiple books and must determine if each book's reading log is consistent. For each book, the reading log is represented by a sequence of page counts recorded over consecutive days. The log is considered consistent if the page counts never decrease, i.e., if for a sequence \(a_1, a_2, \dots, a_N\) it holds that \(a_1 \le a_2 \le \cdots \le a_N\). Otherwise, the log is inconsistent.

inputFormat

The input is read from standard input (stdin). The first line contains a single integer \(T\) representing the number of books. For each book, there are two lines:

• The first line contains a string \(\text{ISBN}\) (without spaces) and an integer \(N\) representing the number of days.
• The second line contains \(N\) space-separated integers denoting the page counts for each day in the order they were recorded.

outputFormat

For each book, output a single line to standard output (stdout) containing the ISBN and the word "YES" if the sequence of page counts is non-decreasing, or "NO" otherwise. The ISBN and the result are separated by a space.
