Worm can move both left and right. Stop for a while and think about it.

Just take two books and try - you will find answer immediately

I fully agree with you.How could the answer for sample input be 2.

n=0
Answer 10

Ok, looks like in my case the format of input data in tests #2 and #6 is differ from the one in the example. Accepted Go code is:


package main

import (
    "fmt"
    "sort"
)

type city struct {
    n, x, y int
}

func main() {
    var n int
    fmt.Scan(&n)
    m := make([]city, n)

    for i := 0; i < n; i++ {
        m[i].n = i + 1
        fmt.Scan(&m[i].x, &m[i].y)
    }

    sort.Slice(m, func(i, j int) bool {
        if m[i].x < m[j].x {
            return true
        }
        return false
    })

        for i := 0; i < n; i += 2 {
        fmt.Println(m[i].n, m[i+1].n)
    }
}

Hi,

What about the scenario where both players have flush ? In texas holdem whosoever has higher highest card wins and if they are the same then it's a tie. So what should be the answer for the following test case.

4C 6C 8C
3H 4H 8H
AS AD

Mine is Artyom because both player's best hand is eight high flush (even though the next best card of sasha (6) is greater than next best card of dima (4)).

First test different
