Hello guys,

I recently submitted a problem which generated the following error:

I looked up online and found an article saying this arises due to segmentation fault. When I declared all variables globally, the error persisted.

The only difference was that instead of WA I got RTE. Could someone pls help me with this issue?

P.S: The submission ID is #177257400 and the problem statement is this
