There are some stones in different positions on the X-axis. You are given an integer array stones
, the positions of the stones.
Call a stone an endpoint stone if it has the smallest or largest position. In one move, you pick up an endpoint stone and move it to an unoccupied position so that it is no longer an endpoint stone.
\n\nstones = [1,2,5]
, you cannot move the endpoint stone at position 5
, since moving it to any position (such as 0
, or 3
) will still keep that stone as an endpoint stone.The game ends when you cannot make any more moves (i.e., the stones are in three consecutive positions).
\n\nReturn an integer array answer
of length 2
where:
answer[0]
is the minimum number of moves you can play, andanswer[1]
is the maximum number of moves you can play.\n
Example 1:
\n\n\nInput: stones = [7,4,9]\nOutput: [1,2]\nExplanation: We can move 4 -> 8 for one move to finish the game.\nOr, we can move 9 -> 5, 4 -> 6 for two moves to finish the game.\n\n\n
Example 2:
\n\n\nInput: stones = [6,5,4,3,10]\nOutput: [2,3]\nExplanation: We can move 3 -> 8 then 10 -> 7 to finish the game.\nOr, we can move 3 -> 7, 4 -> 8, 5 -> 9 to finish the game.\nNotice we cannot move 10 -> 2 to finish the game, because that would be an illegal move.\n\n\n
\n
Constraints:
\n\n3 <= stones.length <= 104
1 <= stones[i] <= 109
stones
are unique.在 X 轴上有一些不同位置的石子。给定一个整数数组 stones
表示石子的位置。
如果一个石子在最小或最大的位置,称其为 端点石子。每个回合,你可以将一颗 端点石子 拿起并移动到一个未占用的位置,使得该石子不再是一颗 端点石子。
\n\nstones = [1,2,5]
这样,你将 无法 移动位于位置 5
的端点石子,因为无论将它移动到任何位置(例如 0
或 3
),该石子都仍然会是端点石子。当你无法进行任何移动时,即,这些石子的位置连续时,游戏结束。
\n\n以长度为 2 的数组形式返回答案,其中:
\n\nanswer[0]
是你可以移动的最小次数answer[1]
是你可以移动的最大次数。\n\n
示例 1:
\n\n\n输入:[7,4,9]\n输出:[1,2]\n解释:\n我们可以移动一次,4 -> 8,游戏结束。\n或者,我们可以移动两次 9 -> 5,4 -> 6,游戏结束。\n\n\n
示例 2:
\n\n\n输入:[6,5,4,3,10]\n输出:[2,3]\n解释:\n我们可以移动 3 -> 8,接着是 10 -> 7,游戏结束。\n或者,我们可以移动 3 -> 7, 4 -> 8, 5 -> 9,游戏结束。\n注意,我们无法进行 10 -> 2 这样的移动来结束游戏,因为这是不合要求的移动。\n\n\n
