For problem statement at 1000-1999/1500-1599/1530-1539/1539/problemF.txt this is a correct solution, but verifier at 1000-1999/1500-1599/1530-1539/1539/verifierF.go ends with case 1: runtime error: exit status 2
panic: runtime error: index out of range [46] with length 16

goroutine 1 [running]:
main.main()
	/tmp/build-393145303/solution.go:112 +0x6f4


exit status 1 can you fix the verifier? package main
