return dinamic data string in golang-CodePudding

package main

import (
    "fmt"
)

func FindSimilarData(input string, data ...string) string {
same := ""
    for _, d := range data {
        fmt.Println(d)

        if (d) == input {
            same  = d
            fmt.Println(d)
            fmt.Println(same)
        }
    }
    return "" 
}

func main() {
    fmt.Println(FindSimilarData("iphone", "laptop", "iphone 13", "iphone 12", "iphone 12 pro"))
}

i want to return the data type string which has similar data, i was trying to use strings. Contains but it only returns the boolean type. can anyone give an example for this one, thanks before

If strings.Contains returns true you can append it on a output string and return the string.

func FindSimilarData(input string, data ...string) string {
    same := ""
    for _, d := range data {
        fmt.Println(d)

        if strings.Contains(d, input) {
            if len(same) != 0 {
                same  = ","
            }
            same  = d
        }
    }
    return same
}
