It was nice. The first 7 minutes were introduction and then half hour for coding question. The interviewer was nice and gave the one hint I had needed to do the question. Overall good experience.
Preguntas de entrevista [1]
Pregunta 1
We have a m x n 2D grid initialized with three possible values:
-1 - An obstacle.
0 - An exit.
INF - An empty room. We use the value 2^31 - 1 = 2147483647 to represent INF as you may assume that the distance to an exit is less than 2147483647.
We want to fill each empty room with the distance to its nearest exit. If it is impossible to reach an exit, it should be filled with INF.
Example:
Given the 2D grid:
INF -1 0 INF
INF INF INF -1
INF -1 INF -1
0 -1 INF INF
We expect the output 2D grid as:
3 -1 0 1
2 2 1 -1
1 -1 2 -1
0 -1 3 4
