For problem statement at 1000-1999/1400-1499/1490-1499/1491/problemA.txt this is a correct solution, but verifier at 1000-1999/1400-1499/1490-1499/1491/verifierA.go ends with oracle error on case 1: exec: "oracleA.bin": executable file not found in $PATH

exit status 1 can you fix the verifier? package main
