Go Language - Program to find the duplicate words in a string

Hello everyone, today we need to find out the duplicate words present in the string and print those words.

Example 1: Program to find the duplicate words in a given string

//Program to find the duplicate words in a string
package main
import (
    "fmt"
    "strings"
)
// Main function
func main() {
    str := "hola hello hi hola good sleep hello hi night morning"
    //Converts the string into lowercase
    strl := strings.ToLower(str)
    //Split the string into words
    words := strings.Split(strl, " ")
    fmt.Println("Duplicate words in a given string are, \n")
    for i := 0; i < len(words); i++ {
        count := 1
        for j := i + 1; j < len(words); j++ {
            if words[i] == words[j] {
                count++
                //Set words[j] to 0 to avoid printing visited word
                words[j] = "0"
            }
        }
        //Displays the duplicate word if count is greater than 1
        if count > 1 && words[i] != "0" {
            fmt.Println(words[i])
        }
    }
}

Output:

Example 2: Program to count duplicate words from given String

//Program to find the duplicate words in a string
package main
import (
    "fmt"
    "strings"
)
// Main function
func main() {
    str := "hola hello hi hola good sleep hello hi night morning hi"
    //Converts the string into lowercase
    strl := strings.ToLower(str)
    //Split the string into words
    words := strings.Split(strl, " ")
    fmt.Println("Duplicate words in a given string are, \n")
    for i := 0; i < len(words); i++ {
        count := 1
        for j := i + 1; j < len(words); j++ {
            if words[i] == words[j] {
                count++
                //Set words[j] to 0 to avoid printing visited word
                words[j] = "0"
            }
        }
        //Displays the duplicate word if count is greater than 1
        if count > 1 && words[i] != "0" {
            fmt.Println(words[i], count)
        }
    }
}
