OJ Board

I get AC at last. I changed the array from integer to char. That means I checked if it is 1 and now I check if it is '1'.

I've tried all the test case for 352 on this board and I can get right answer. But I don't know why I keep WA while upload to online judge. Please help. I use BFS first and now I am using DFS, I can pass the test cases in both algorithms but still can't pass the online judge. Thank you very much. co...
