For problem statement at 0-999/900-999/900-909/903/problemD.txt this is a correct solution, but verifier at 0-999/900-999/900-909/903/verifierD.go ends with All tests passed can you fix the verifier? ```go
package main

import (
	"bufio"
	"fmt"
	"os"
	"strconv"
)

func main() {
	scanner := bufio.NewScanner(os.Stdin)
	scanner.Split(bufio.ScanWords)

	if !scanner.Scan() {
		return
	}
	n, _ := strconv.Atoi(scanner.Text())

	cnt := make(map[int]int, n)
	var ans, sum int64

	for i := 0; i < n; i++ {
		scanner.Scan()
		x, _ := strconv.Atoi(scanner.Text())
		val := int64(x)

		term := int64(i)*val - sum
		
		cMinus := int64(cnt[x-1])
		cPlus := int64(cnt[x+1])
		correction := cMinus - cPlus
		
		ans += term - correction
		
		sum += val
		cnt[x]++
	}

	fmt.Println(ans)
}
```
