In the first test case, you can color the array as follows: $[\color{red}{5}, \color{black}{4}, \color{red}{5}]$. Your score is $\max([5, 5]) + \text{size}([5, 5]) = 5+2 = 7$. This is the maximum score you can get.

In the second test case, you can color the array as follows: $[\color{red}{4}, \color{black}{5}, \color{red}{4}]$. Your score is $\max([4, 4]) + \text{size}([4, 4]) = 4+2 = 6$. This is the maximum score you can get.

In the third test case, you can color the array as follows: $[\color{red}{3}, \color{black}{3}, \color{red}{3}, \color{black}{3}, \color{red}{4}, \color{black}{1}, \color{black}{2}, \color{red}{3}, \color{black}{4}, \color{red}{5}]$. Your score is $\max([3, 3, 4, 3, 5]) + \text{size}([3, 3, 4, 3, 5]) = 5+5 = 10$. This is the maximum score you can get.
