There is a dungeon with n x m rooms arranged as a grid.
You are given a 2D array moveTime of size n x m, where moveTime[i][j] represents the minimum time in seconds when you can start moving to that room. You start from the room (0, 0) at time t = 0 and can move to an adjacent room. Moving between adjacent rooms takes one second for one move and two seconds for the next, alternating between the two.
Return the minimum time to reach the room (n - 1, m - 1).
Two rooms are adjacent if they share a common wall, either horizontally or vertically.
\n\n\n
Example 1:
\n\nInput: moveTime = [[0,4],[4,4]]
\n\nOutput: 7
\n\nExplanation:
\n\nThe minimum time required is 7 seconds.
\n\nt == 4, move from room (0, 0) to room (1, 0) in one second.t == 5, move from room (1, 0) to room (1, 1) in two seconds.Example 2:
\n\nInput: moveTime = [[0,0,0,0],[0,0,0,0]]
\n\nOutput: 6
\n\nExplanation:
\n\nThe minimum time required is 6 seconds.
\n\nt == 0, move from room (0, 0) to room (1, 0) in one second.t == 1, move from room (1, 0) to room (1, 1) in two seconds.t == 3, move from room (1, 1) to room (1, 2) in one second.t == 4, move from room (1, 2) to room (1, 3) in two seconds.Example 3:
\n\nInput: moveTime = [[0,1],[1,2]]
\n\nOutput: 4
\n\n
Constraints:
\n\n2 <= n == moveTime.length <= 7502 <= m == moveTime[i].length <= 7500 <= moveTime[i][j] <= 109有一个地窖，地窖中有 n x m 个房间，它们呈网格状排布。
给你一个大小为 n x m 的二维数组 moveTime ，其中 moveTime[i][j] 表示在这个时刻 以后 你才可以 开始 往这个房间 移动 。你在时刻 t = 0 时从房间 (0, 0) 出发，每次可以移动到 相邻 的一个房间。在 相邻 房间之间移动需要的时间为：第一次花费 1 秒，第二次花费 2 秒，第三次花费 1 秒，第四次花费 2 秒……如此 往复 。
请你返回到达房间 (n - 1, m - 1) 所需要的 最少 时间。
如果两个房间有一条公共边（可以是水平的也可以是竖直的），那么我们称这两个房间是 相邻 的。

示例 1：
\n\n输入：moveTime = [[0,4],[4,4]]
\n\n输出：7
\n\n解释：
\n\n需要花费的最少时间为 7 秒。
\n\nt == 4 ，从房间 (0, 0) 移动到房间 (1, 0) ，花费 1 秒。t == 5 ，从房间 (1, 0) 移动到房间 (1, 1) ，花费 2 秒。示例 2：
\n\n输入：moveTime = [[0,0,0,0],[0,0,0,0]]
\n\n输出：6
\n\n解释：
\n\n需要花费的最少时间为 6 秒。
\n\nt == 0 ，从房间 (0, 0) 移动到房间 (1, 0) ，花费 1 秒。t == 1 ，从房间 (1, 0) 移动到房间 (1, 1) ，花费 2 秒。t == 3 ，从房间 (1, 1) 移动到房间 (1, 2) ，花费 1 秒。t == 4 ，从房间 (1, 2) 移动到房间 (1, 3) ，花费 2 秒。示例 3：
\n\n输入：moveTime = [[0,1],[1,2]]
\n\n输出：4
\n\n\n
提示：
