Each test contains multiple test cases. The first line contains a single integer $$$t$$$ ($$$1 \leq t \leq 10^4$$$) — the number of test cases. The description of the test cases follows. The first line of each test case contains an integer $$$n$$$ ($$$2 \le n \le 2 \cdot 10 ^ 5$$$) — the length of array $$$a$$$. The se...

You are given an array $$$a$$$ of length $$$n$$$. We define the equality of the array as the number of indices $$$1 \le i \le n - 1$$$ such that $$$a_i = a_{i + 1}$$$. We are allowed to do the following operation: Select two integers $$$i$$$ and $$$x$$$ such that $$$1 \le i \le n - 1$$$ and $$$1 \le x \le 10^9$$$. The...

NoteIn the first test case, we can select $$$i=2$$$ and $$$x=2$$$ to form $$$[1, 2, 2, 1, 1]$$$. Then, we can select $$$i=3$$$ and $$$x=3$$$ to form $$$[1, 2, 3, 3, 1]$$$.In the second test case, we can select $$$i=3$$$ and $$$x=100$$$ to form $$$[2, 1, 100, 100, 2]$$$.
