For problem statement at 1000-1999/1200-1299/1220-1229/1220/problemB.txt this is a correct solution, but verifier at 1000-1999/1200-1299/1220-1229/1220/verifierB.go ends with runtime error: exit status 2
output:
panic: runtime error: integer divide by zero

goroutine 1 [running]:
main.main()
	/tmp/build-4087638239/solution.go:68 +0x458

exit status 1 can you fix the verifier? package main
