For problem statement at 1000-1999/1100-1199/1180-1189/1183/problemA.txt this is a correct solution, but verifier at 1000-1999/1100-1199/1180-1189/1183/verifierA.go ends with oracle runtime error on case 1: exec: "oracleA": executable file not found in $PATH
exit status 1 can you fix the verifier? package main

import "fmt"

func digitSum(n int) int {
	s := 0
	for n > 0 {
		s += n % 10
		n /= 10
	}
	return s
}

func main() {
	var a int
	fmt.Scan(&a)
	for digitSum(a)%4 != 0 {
		a++
	}
	fmt.Println(a)
}
