Use HasPrefix, HasSuffix and Contains in Golang

package main

import (
    "fmt"
    "strings"
)

func main() {

    s1 := "laptop"
    s2 := "la"
    s3 := "top"
    s4 := "ap"

    result1 := strings.HasPrefix(s1, s2)
    fmt.Println("result 1: ", result1)

    result2 := strings.HasSuffix(s1, s3)
    fmt.Println("result 2: ", result2)

    result3 := strings.Contains(s1, s4)
    fmt.Println("result 3: ", result3)

}    

Output

result 1:  true
result 2:  true
result 3:  true
