Problem Statement

You will be given an integer a and a string s consisting of lowercase English letters as input.

Write a program that prints s if a is not less than 3200 and prints red if a is less than 3200.

Constraints

2800 \leq a < 5000

s is a string of length between 1 and 10 (inclusive).

Each character of s is a lowercase English letter.

Input

Input is given from Standard Input in the following format:

a
s

Output

If a is not less than 3200, print s; if a is less than 3200, print red.

Sample Input 1

3200
pink

Sample Output 1

pink

a = 3200 is not less than 3200, so we print s = pink.

Sample Input 2

3199
pink

Sample Output 2

red

a = 3199 is less than 3200, so we print red.

Sample Input 3

4049
red

Sample Output 3

red

a = 4049 is not less than 3200, so we print s = red.

Solution in Go (1.6) (judge verdict: Wrong Answer)

package main

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

var sc = bufio.NewScanner(os.Stdin)

func nextLine() string {
	sc.Scan()
	return sc.Text()
}

func nextInt() int {
	sc.Scan()
	i, err := strconv.Atoi(sc.Text())
	if err != nil {
		panic(err)
	}
	return i
}

func main() {
	sc.Split(bufio.ScanWords)
	a, s := nextInt(), nextLine()
	if a > 3200 {
		fmt.Println(s)
	} else {
		fmt.Println("red")
	}
}
