There is only one character 'A' on the screen of a notepad. You can perform one of two operations on this notepad for each step:

\n\n\n\n

Given an integer n, return the minimum number of operations to get the character 'A' exactly n times on the screen.

\n\n

 

\n

Example 1:

\n\n
\nInput: n = 3\nOutput: 3\nExplanation: Initially, we have one character 'A'.\nIn step 1, we use Copy All operation.\nIn step 2, we use Paste operation to get 'AA'.\nIn step 3, we use Paste operation to get 'AAA'.\n
\n\n

Example 2:

\n\n
\nInput: n = 1\nOutput: 0\n

最初记事本上只有一个字符 'A' 。你每次可以对这个记事本进行两种操作:

\n\n\n\n

给你一个数字 n ,你需要使用最少的操作次数,在记事本上输出 恰好 n 个 'A' 。返回能够打印出 n 个 'A' 的最少操作次数。

\n\n

 

\n\n

示例 1:

\n\n
\n输入:3\n输出:3\n解释:\n最初, 只有一个字符 'A'。\n第 1 步, 使用 Copy All 操作。\n第 2 步, 使用 Paste 操作来获得 'AA'。\n第 3 步, 使用 Paste 操作来获得 'AAA'。\n
\n\n

示例 2:

\n\n
\n输入:n = 1\n输出:0\n
