5,185 graduate developer interview questions shared by candidates

Imagine you have a 6x6 2D array filled with 1s and 0s. The 1s represent walls and the 0s represent empty space. (As if you are looking down at a board game). Step one: Make a method that takes an input of exactly one coordinate on the board. The method returns true if and only if there is a valid empty space for the player to move to from the input, assuming the player can only move up/down/left right and not diagonally Step two: Make another method that returns a boolean. The input should be a coordinate on the board, and the method should return true if from the starting coordinate (the input) the player can move to all available open spaces on the board.
