CF546D Soldier and Number Game

Two soldiers are playing a game. At the beginning, the first of them chooses a positive integer $n$ and gives it to the second soldier. Then, the second one tries to make the maximum possible number of rounds. Each round consists of choosing a positive integer $x > 1$, such that $n$ is divisible by $x$, and replacing $n$ with $\frac{n}{x}$. When $n$ becomes equal to $1$ and there are no more possible valid moves, the game is over, and the score of the second soldier is equal to the number of rounds he performed. To make the game more interesting, first soldier chooses $ n $ of form $ a!/b! $ for some positive integer $ a $ and $ b $ ( $ a>=b $ ). Here by $ k! $ we denote the factorial of $ k $ that is defined as a product of all positive integers not large than $ k $ . What is the maximum possible score of the second soldier?

First line of input consists of single integer $ t $ ( $ 1

For each game output a maximum score that the second soldier can get.
