For problem statement at 0-999/400-499/410-419/416/problemB.txt this is a correct solution, but verifier at 0-999/400-499/410-419/416/verifierB.go ends with All tests passed can you fix the verifier? package main

	"bufio"
	"io"

		num := 0
		for idx < len(data) && data[idx] > ' ' {
			num = num*10 + int(data[idx]-'0')
			idx++
		}
		return num
	}
