I didnt read your code completely, but in the first line of your solve() function, you mentioned _odd and _even can contain the value -1 . so it may happen something like this, dp[idx][-1][1][last] ..

The following update fixed your solution.

70350376

The exit code in the run-time error is a segmentation fault that is raised when one of the indices of the dp array is out-of-range. Your soluton obviously processed the memory locations outside the valid memory space allocated to the dp array in your machine without raising a segmentation fault. This may happen in some machines, but the fault may be detected when running the code in another place.

    or see this and fix that code (always debug by yourself please)

    next time use codeforces CUSTOM INVOCATION to check your RTE code not on your computer
