Good people don't want other people to guess. Good people show task number and type of error and test number - is it definitely "run-time error"?

I guess it is "1001 reverse root". In this case you MUST read and understand task. Does task say you have 4 and only 4 integers to read? Task says you have unknown number of 64 bit longs to read. Task also says you should write output in reverse order.

Also I think you haven't check task sample locally. Your program should fail during reading "876652098643267843" as 32 bit int.
