In his dream, Cocoly would go on a long holiday with no worries around him. So he would try out for many new things, such as... being a carpenter. To learn it well, Cocoly decides to become an apprentice of Master, but in front of him lies a hard task waiting for him to solve.

Cocoly is given an array $a_1, a_2,\ldots, a_n$. Master calls a set of integers $S$ stable if and only if, for any possible $u$, $v$, and $w$ from the set $S$ (note that $u$, $v$, and $w$ do not necessarily have to be pairwise distinct), sticks of length $u$, $v$, and $w$ can form a non-degenerate triangle$^{\text{∗}}$.

Cocoly is asked to partition the array $a$ into several (possibly, $1$ or $n$) non-empty continuous subsegments$^{\text{†}}$, such that: for each of the subsegments, the set containing all the elements in it is stable.

Master wants Cocoly to partition $a$ in at least two different$^{\text{‡}}$ ways. You have to help him determine whether it is possible.

Input

Each test contains multiple test cases. The first line of the input contains a single integer $t$ ($1 \leq t \leq 200$) — the number of test cases. The description of test cases follows.

The first line of each test case contains a single integer $n$ ($2 \leq n \leq 200$) — the length of the array $a$.

The second line contains $n$ integers $a_1,a_2,\ldots,a_n$ ($1 \leq a_i \leq 10^5$) — the elements in the array $a$.

Output

For each test case, print $\texttt{YES}$ if there are at least two ways to partition $a$, and $\texttt{NO}$ otherwise.

You can output the answer in any case (upper or lower). For example, the strings $\texttt{yEs}$, $\texttt{yes}$, $\texttt{Yes}$, and $\texttt{YES}$ will be recognized as positive responses.

In the first test case, here are two possible partitions:

• $[2, 3], [5, 7]$, since $[2, 3]$ is stable because sticks of lengths $(2, 2, 2), (2, 2, 3), (2, 3, 3), (3, 3, 3)$ respectively can all form non-degenerate triangles. $[5, 7]$ is stable because sticks of lengths $(5, 5, 5), (5, 5, 7), (5, 7, 7), (7, 7, 7)$ respectively can all form non-degenerate triangles.
• and $[2], [3, 5], [7]$, since $[2]$ is stable because sticks of lengths $(2, 2, 2)$ respectively can form a non-degenerate triangle. $[3, 5]$ is stable because sticks of lengths $(3, 3, 3), (3, 3, 5), (3, 5, 5), (5, 5, 5)$ respectively can all form non-degenerate triangles. $[7]$ is stable because sticks of lengths $(7, 7, 7)$ respectively can form a non-degenerate triangle.

Note that some other partitions also satisfy the constraints, such as $[2], [3], [5], [7]$ and $[2], [3], [5, 7]$.

In the second test case, Cocoly can only partition each element as a single subsegment, resulting in $[115], [9], [2], [28]$. Since we only have one possible partition, the answer is $\texttt{NO}$.

In the third test case, please note that the partition $[8, 4], [1], [6], [2]$ does not satisfy the constraints, because $\{8, 4\}$ is not a stable set: sticks of lengths $4$, $4$, and $8$ cannot form a non-degenerate triangle.
