不是超时，而是有运行中出现的错误，比如数组溢了或者读数据数据不够，或者除数为0了之类的错误。
Runtime Error (RE): Your program has failed during the execution. Possible causes include illegal file access, stack overflow, out of range in pointer reference, floating point exception, division by zero and many others. Programs that stay not responding for a long time (not consuming CPU cycles) may also be considered to have encountered runtime errors.
