The onlyRegardless of the problem and its solution, the ONLY line that changes between the 2 submissions is the way I check if the state was calculated before or not. When I check it using `if (ret != -1)` it gives TLE, but when I check it using visit array `is (visit[i][j] == vid)` it passes. I don't even remove the extra memset for memoization array in each testcase when using the visit array. Why would this very small change result in that huge difference in time?
