For problem statement at 0-999/400-499/470-479/475/problemD.txt this is a correct solution, but verifier at 0-999/400-499/470-479/475/verifierD.go ends with oracle failure on case 1: runtime error: fork/exec .//home/ubuntu/codeforces/0-999/400-499/470-479/475/oracleD: no such file or directory

exit status 1 can you fix the verifier? ```go
package main

	"bufio"
	"os"
)

type pair struct {
	g int
	c int64
}

func gcd(a, b int) int {
	for b != 0 {

	}
	return a

	}

	n := readInt()
