Is there anyway to make the return text of a boolean function not show in the terminal-CodePudding

Im doing a project for school where I have to use binary search to figure out if a specific number is present in a string of numbers. I am new to coding and am trying to figure out a way to have "true" not show up in the terminal. Is there a way to do this or do I have to remove the boolean function. I know I cannot remove the "return true" from the code because it stops it from working but I want the output to just be the code I am printing not the "true"

func BinarySearch(target int, input []int) bool {

    first := 0
    last := len(input) - 1

    for first <= last{

        median := (first   last) / 2

        if input[median] < target {
            first = median   1
        }else{
            last = median - 1
        }

    }

    if first == len(input) || input[first] != target {
        fmt.Println("The searched integer", target, "was not found")
    } else {
        fmt.Println("The searched integer", target, "was found")
    }

    return true

}

I have input the text I want to print but do not know what to do about the return

You can just do that by removing the bool after the params of the function, because basically you were telling that the function must return a boolean, while you were going to use it as a void. Dont forget also to pre-sort your input prior to passing it to your function. Best of luck

func BinarySearch(target int, input []int) {

    first := 0
    last := len(input) - 1

    for first <= last{

        median := (first   last) / 2

        if input[median] < target {
            first = median   1
        }else{
            last = median - 1
        }

    }

    if first == len(input) || input[first] != target {
        fmt.Println("The searched integer", target, "was not found")
    } else {
        fmt.Println("The searched integer", target, "was found")
    }
}

I would probably do something like this:

package main

import (
    "fmt"
)

func main() {
    orderedList := []int{1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25}

    for i := 0; i < 27; i   {
        var slug string
        if found := BinarySearch(i, orderedList); !found {
            slug = "not "
        }
        fmt.Printf("%d is %s in the list\n", i, slug)
    }
}

func BinarySearch(target int, values []int) (found bool) {
    lo := 0
    hi := len(values)

    for hi > lo {
        mid := lo   (hi-lo)/2

        if values[mid] < target {
            lo = mid   1
        } else {
            hi = mid
        }

    }

    found = lo < len(values) && target == values[lo]
    return found
}
