For problem statement at 1000-1999/1800-1899/1860-1869/1861/problemD.txt this is a correct solution, but verifier at 1000-1999/1800-1899/1860-1869/1861/verifierD.go ends with Wrong answer on test 1
Input:1
8
0 1 6 0 5 13 16 0
Expected:3
Got:2

exit status 1 can you fix the verifier? ```go
package main

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

func main() {
	in := bufio.NewReader(os.Stdin)
	out := bufio.NewWriter(os.Stdout)
	defer out.Flush()

	var t int
	fmt.Fscan(in, &t)
	for ; t > 0; t-- {
		var n int
		fmt.Fscan(in, &n)
		a := make([]int64, n)
		for i := 0; i < n; i++ {
			fmt.Fscan(in, &a[i])
		}
		ans := 0
		for i := 0; i < n-1; i++ {
			if a[i] >= a[i+1] {
				ans++
			}
		}
		fmt.Fprintln(out, ans)
	}
}
```
