在golang中读取行

Question

There are so many option to do this in Go. For example:

scanner := bufio.NewScanner(os.Stdin)
for scanner.Scan() {
    fmt.Println(scanner.Text())
}

or

reader := bufio.NewReader(os.Stdin)
text, _ := reader.ReadString('
')

Neither is working in my case. I am unable to find the reason why new line scan is not working.

Here's the question I'm working on: https://www.hackerrank.com/challenges/30-dictionaries-and-maps

And here's my code:

package main
import (
    "fmt"
    "bufio"
    "os"
    "strings"
)

func main() {
    var count int
    fmt.Scan(&count)

    m := make(map[string]string)
    for i := 0; i<count; i++{
        reader := bufio.NewReader(os.Stdin)
        text,err := reader.ReadString('
')
        if err != nil {
           fmt.Println(err)
        }
        value := strings.Fields(text)
        m[value[0]] = value[1]
    }
    var names []string
    for i := 0; i<count; i++{
        var name string
        fmt.Scan(&name)
        names = append(names,name)
    }

    for j:= 0; j<len(names);j++{
        if m[names[j]] != ""{
            fmt.Println(names[j] +" = "+ m[names[j]])
        }else{
            fmt.Println("Not found")
        }

    }

}

It is working in my editor, but when I use the question's input, it doesn't work.

As requested in the comments, here was my working example:

package main

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

func main() {
    phonebook := make(map[string]int)

    var count int
    fmt.Scan(&count)
    for i := 0; i < count; i++ {
        var name string
        var number int
        fmt.Scan(&name, &number)
        phonebook[name] = number
    }

    scanner := bufio.NewScanner(os.Stdin)
    for scanner.Scan() {
        name := scanner.Text()
        if number, ok := phonebook[name]; ok {
            fmt.Printf("%s=%d
", name, number)
        } else {
            fmt.Println("Not found")
        }
    }
}
