Each test contains multiple test cases. The first line will contain a single integer $$$t$$$ $$$(1 \leq t \leq 10000)$$$ — the number of test cases. Then $$$t$$$ test cases follow. The first line of each test case contains a single integer $$$n$$$ $$$(2 \leq n \leq 2 \cdot 10^5)$$$ — the size of the array $$$a$$$. The ...

For each test case, first output a line containing a single integer $$$m$$$ — minimum number of operations required. Then ouput a line consist of $$$n$$$ integers — the resulting array after the operations. Note that this array should differ in exactly $$$m$$$ elements from the initial array.

You are given an array $$$a$$$ of size $$$n$$$. Each element in this array is an integer between $$$1$$$ and $$$10^9$$$.You can perform several operations to this array. During an operation, you can replace an element in the array with any integer between $$$1$$$ and $$$10^9$$$. Output the minimum number of operations ...

NoteIn the first example, the array contains no local maximum, so we don't need to perform operations.In the second example, we can change $$$a_2$$$ to $$$3$$$, then the array don't have local maximums.
