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 exactly one second.
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.
Example 1:
Input: moveTime = [[0,4],[4,4]]
Output: 6
Explanation:
The minimum time required is 6 seconds.
t == 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 one second.Example 2:
Input: moveTime = [[0,0,0],[0,0,0]]
Output: 3
Explanation:
The minimum time required is 3 seconds.
t == 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 one second.t == 2
, move from room (1, 1)
to room (1, 2)
in one second.Example 3:
Input: moveTime = [[0,1],[1,2]]
Output: 3
Constraints:
2 <= n == moveTime.length <= 50
2 <= m == moveTime[i].length <= 50
0 <= moveTime[i][j] <= 109
