## Problem Statement

#### GRID is initialised by 3 possible values,

``````-1 represents a glacier crack.
0 represents basecamp.
INF represents safe passage (INF = 2^31 -1 = 2147483647 so you may assume the distance of basecamp is less than INF).
``````

#### Note: Sam can not travel through cracks.

##### Example:
``````Input:
3 3
-1 0 -1
2147483647 2147483647 2147483647
0 -1 -1

Output:
-1 0 -1
1 1 2
0 -1 -1

Explanation:
For the first INF from left to right, the closest base camp is in the bottom left with a distance of 1. For the second INF, the closest base camp is just above with a distance of 1, and for the third INF,  the base camp on the top middle is closest with a distance equal to 2.

##### Explanation Of Sample Input 1 :
``````Test 1:
For the first INF from left to right, the closest base camp is in the bottom left with a distance of 1. For the second INF, the closest base camp is just above with a distance of 1, and for the third INF,  the base camp on the top middle is closest with a distance equal to 2.

Test 2:
For the first INF from above, the closest base camp in the top middle is closest with a distance equal to 1. While for the second INF it is not possible to reach any base camp.
