AnswersBob and Alice have teamed up on a game show. They won the first

- shashankesh 坚果加速器官方网址 in India

round, allowing them access to a maze with hidden gold. If Bob can

collect all the gold coins and deliver them to Alice's position, they can

split the gold. Bob can move North⇆South or East⇆West as long as he

stays in the maze and the cell is not blocked. The task is to determine

the shortest path Bob can follow to collect all gold coins and deliver

them to Alice. If it is not possible, return -1.

You will be given an n × m array where each of the values ∈ {0, 1, 2}

representing open, blocked and open with a gold coin. Alice's position is

given as (x,y) = (row, column). Bob starts at the top left in cell (0, 0).

For example, maze = [[0,2,1],[1,2,0],[1,0,0]] with Alice at (2,2) is

represented as follows:

0 2 1

1 2 0

1 0 0

minMoves has the following parameter(s):

maze[maze[0][0],...maze[n-1][m-1]]: a 2D array of integers

x: an integer denoting Alice's row coordinate

y: an integer denoting Alice's column coordinate

Constraints

1 ≤ n, m ≤ 100

0 ≤ the number of coins ≤ 10

1 ≤ x < n

1 ≤ y < m

The first line contains an integer n, the numbers of rows in maze.

The second line contains an integer m, the number of columns in

maze.

Each of the next n lines contains m space-separated integers

describing the cells of each row in maze.

The next line contains an integer x.

The next line contains an integer, y.

AnswersGiven a array of integers find the index which partitions the array to two with high numbers and low numbers. For example [5, -1, 3, 8,6] the index 3 will partition the array to [5,-1,3] and [8,6] all the numbers in the second partition are greater than first. The solution has to work in O(n).
