You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 1579G.go
    path of file: ./repos/codeforces-go/main/1500-1599
    
    the code of the file until where you have to start completion: package main

import (
	"bufio"
	. "fmt"
	"io"
)

// https://space.bilibili.com/206214
func CF1579G(_r io.Reader, _w io.Writer) {
	in := bufio.NewReader(_r)
	out := bufio.NewWriter(_w)
	defer out.Flush()
	min := func(a, b int) int {
		if a > b {
			return b
		}
		return a
	}
	max := func(a, b int) int {
		if b > a {
			return b
		}
		return a
	}
	const inf int = 1e9
	const mx = 2001
	pre := make([]int, mx)
	f := make([]int, mx)

	var T, n, v int
	for Fscan(in, &T); T > 0; T-- {
		for i := range pre {
			pre[i] = inf
