For problem statement at 1000-1999/1300-1399/1310-1319/1310/problemE.txt this is a correct solution, but verifier at 1000-1999/1300-1399/1310-1319/1310/verifierE.go ends with # command-line-arguments
./1310E.go:160:12: declared and not used: same
failed to build reference: exit status 1
exit status 1 can you fix the verifier? package main
