Replace in Go

In Go, you can replace a substring within a string using the strings.Replace() function. This function takes four arguments - the original string, the old substring to be replaced, the new substring to replace the old substring, and the number of replacements to be made (use -1 for all occurrences).

Here's an example code snippet:

package main
import (

    "fmt"

    "strings"

)
func main() {

    originalString := "I love pizza and pizza is awesome"

    newString := strings.Replace(originalString, "pizza", "ice cream", -1)

    fmt.Println("Original string:", originalString)

    fmt.Println("New string:", newString)

}

This will output:

Original string: I love pizza and pizza is awesome
New string: I love ice cream and ice cream is awesome

In this example, we replace the substring "pizza" with "ice cream" in the original string using the strings.Replace() function. The -1 argument tells the function to replace all occurrences of "pizza". The new string is stored in a variable called newString, which is then printed to the console.
