For problem statement at 0-999/800-899/860-869/863/problemB.txt this is a correct solution, but verifier at 0-999/800-899/860-869/863/verifierB.go ends with All 100 tests passed. can you fix the verifier? ```go
package main

import (
	"fmt"
	"sort"
)

func main() {
	var n int
	fmt.Scan(&n)
	m := 2 * n
	w := make([]int, m)
	for i := 0; i < m; i++ {
		fmt.Scan(&w[i])
	}
	sort.Ints(w)

	minInstability := 1000000000

	for i := 0; i < m; i++ {
		for j := i + 1; j < m; j++ {
			var temp []int
			for k := 0; k < m; k++ {
				if k != i && k != j {
					temp = append(temp, w[k])
				}
			}

			currentInstability := 0
			for k := 0; k < len(temp); k += 2 {
				currentInstability += temp[k+1] - temp[k]
			}

			if currentInstability < minInstability {
				minInstability = currentInstability
			}
		}
	}

	fmt.Println(minInstability)
}
```
