For problem statement at 1000-1999/1000-1099/1030-1039/1038/problemC.txt this is a correct solution, but verifier at 1000-1999/1000-1099/1030-1039/1038/verifierC.go ends with All 100 tests passed can you fix the verifier? ```go
package main

import (
	"bufio"
	"fmt"
	"os"
	"sort"
)

func main() {
	scanner := bufio.NewReader(os.Stdin)
	var n int
	fmt.Fscan(scanner, &n)
	
	a := make([]int, n)
	for i := 0; i < n; i++ {
		fmt.Fscan(scanner, &a[i])
	}
	
	b := make([]int, n)
	for i := 0; i < n; i++ {
		fmt.Fscan(scanner, &b[i])
	}
	
	sort.Slice(a, func(i, j int) bool { return a[i] > a[j] })
	sort.Slice(b, func(i, j int) bool { return b[i] > b[j] })
	
	i, j := 0, 0
	diff := 0
	turn := 0
	
	for i < n || j < n {
		if turn == 0 {
			if i < n && (j >= n || a[i] >= b[j]) {
				diff += a[i]
				i++
			} else if j < n {
				j++
			}
		} else {
			if j < n && (i >= n || b[j] >= a[i]) {
				diff -= b[j]
				j++
			} else if i < n {
				i++
			}
		}
		turn ^= 1
	}
	
	fmt.Println(diff)
}
```
