This looks like a terrible bug to me. Not sure how often/likely will this bug be triggered.
Would it make sense if we ask the Code Jam team to use higher/latest Perl version? or lower version if higher version is not feasible. The 5.28.0 was released back in 2018 and seems pretty old now. 在2021年4月26日星期一 UTC-7 上午6:28:05<cho...@matfyz.cz> 写道： > I'm getting the same wrong output in Perl 5.28.1 which is the version Code > Jam > uses.
