Go Slice - Program to Find Largest & Smallest Element

Example 1: Finding the largest element in a Slice

// Go program to find largest number in a Slice
package main
import "fmt"
// Main function
func main() {
    // Let’s define an slice first
    arr := []int{2, 11, 22, 5, 6, 3, 1, 9}
    fmt.Println("Largest Number:", LargestNumber(arr))
    //Another Example
    anotherarr := []int{144, 666, 99, 677, 433, 422, 255}
    fmt.Println("Largest Number:", LargestNumber(anotherarr))
}
func LargestNumber(arr []int) int {
    var temp int
    for i := 0; i < len(arr); i++ {
        for j := i + 1; j < len(arr); j++ {
            if arr[i] > arr[j] {
                temp = arr[i]
                arr[i] = arr[j]
                arr[j] = temp
            }
        }
    }
    return arr[len(arr)-1]
}

Output:

Example 2: Finding the smallest element in a Slice

// Go program to find smallest number in a Slice
package main
import "fmt"
// Main function
func main() {
    // Let’s define a slice first
    arr := []int{2, 11, 22, 5, 6, 3, 1, 9}
    fmt.Println("Smallest Number:", SmallestNumber(arr))
    //Another Example
    anotherarr := []int{144, 666, 99, 677, 433, 422, 22}
    fmt.Println("Smallest Number:", SmallestNumber(anotherarr))
}
func SmallestNumber(arr []int) int {
    var temp int
    for i := 0; i < len(arr); i++ {
        for j := i + 1; j < len(arr); j++ {
            if arr[i] > arr[j] {
                temp = arr[i]
                arr[i] = arr[j]
                arr[j] = temp
            }
        }
    }
    return arr[0]
}

Output:
