Golang：给定句子的缩写

Question

How to find, given a sentence, the acronym of that sentence using GO programming language. For example, “Hello, world!” becomes “HW”. So far I have tried splitting the sentence:

package main

import (
    "bufio"
    "fmt"
    "strings"
    "os"
)
func main() {
    reader := bufio.NewReader(os.Stdin)
    fmt.Print("Enter text: ")
    text, _ := reader.ReadString('
')
    fmt.Print(strings.Split(text," "))
    fmt.Print(strings.Index(text, ))
}

1. Took input from the user
2. Split on the occurrence of white space.
3. What next?

Any help is appreciated.

Thanks

Answer 1

After you have split the strings you need to append the first letter of each word to your result string.

text := "Hello World"
words := strings.Split(text, " ")

res := ""

for _, word := range words {
    res = res + string([]rune(word)[0])
}

fmt.Println(res)

Note that you might need to add some checks to catch the case if the input is empty which results in a [""] from strings.Split.
