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:
