You are given a 0-indexed array of positive integers tasks, representing tasks that need to be completed in order, where tasks[i] represents the type of the ith task.

\n\n

You are also given a positive integer space, which represents the minimum number of days that must pass after the completion of a task before another task of the same type can be performed.

\n\n

Each day, until all tasks have been completed, you must either:

\n\n\n\n

Return the minimum number of days needed to complete all tasks.

\n\n

Example 1:

\n\n
\nInput: tasks = [1,2,1,2,3,1], space = 3\nOutput: 9\nExplanation:\nOne way to complete all tasks in 9 days is as follows:\nDay 1: Complete the 0th task.\nDay 2: Complete the 1st task.\nDay 3: Take a break.\nDay 4: Take a break.\nDay 5: Complete the 2nd task.\nDay 6: Complete the 3rd task.\nDay 7: Take a break.\nDay 8: Complete the 4th task.\nDay 9: Complete the 5th task.\nIt can be shown that the tasks cannot be completed in less than 9 days.\n
\n\n

Example 2:

\n\n
\nInput: tasks = [5,8,8,5], space = 2\nOutput: 6\nExplanation:\nOne way to complete all tasks in 6 days is as follows:\nDay 1: Complete the 0th task.\nDay 2: Complete the 1st task.\nDay 3: Take a break.\nDay 4: Take a break.\nDay 5: Complete the 2nd task.\nDay 6: Complete the 3rd task.\nIt can be shown that the tasks cannot be completed in less than 6 days.\n

给你一个下标从 0 开始的正整数数组 tasks ，表示需要 按顺序 完成的任务，其中 tasks[i] 表示第 i 件任务的 类型 。

\n\n

同时给你一个正整数 space ，表示一个任务完成 后 ，另一个 相同 类型任务完成前需要间隔的 最少 天数。

\n\n

在所有任务完成前的每一天，你都必须进行以下两种操作中的一种：

\n\n\n\n

请你返回完成所有任务所需的 最少 天数。

示例 1：

\n\n
输入：tasks = [1,2,1,2,3,1], space = 3\n输出：9\n解释：\n9 天完成所有任务的一种方法是：\n第 1 天：完成任务 0 。\n第 2 天：完成任务 1 。\n第 3 天：休息。\n第 4 天：休息。\n第 5 天：完成任务 2 。\n第 6 天：完成任务 3 。\n第 7 天：休息。\n第 8 天：完成任务 4 。\n第 9 天：完成任务 5 。\n可以证明无法少于 9 天完成所有任务。\n

示例 2：

\n\n
输入：tasks = [5,8,8,5], space = 2\n输出：6\n解释：\n6 天完成所有任务的一种方法是：\n第 1 天：完成任务 0 。\n第 2 天：完成任务 1 。\n第 3 天：休息。\n第 4 天：休息。\n第 5 天：完成任务 2 。\n第 6 天：完成任务 3 。\n可以证明无法少于 6 天完成所有任务。\n
