Hello everyone, in this tutorial, we will show you how to reverse an array in golang programming language. The example program has been tested and shared in the post.
Function – Reverse an array in Golang
The bellow function reverse() is responsible to reverse a given integer array.
func reverse(numbers []int) []int {
var length int = len(numbers) // getting length of an array
for i := 0; i < length/2; i++ {
temp := numbers[i]
numbers[i] = numbers[length - i - 1]
numbers[length - i - 1] = temp
}
return numbers
}
Full Example
package main
import "fmt"
func main() {
// defining integer array
var numbers []int = []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
// calling reverse function
numbers = reverse(numbers)
// printing the result
fmt.Println(numbers)
}
// function to reverse the given integer array
func reverse(numbers []int) []int {
var length int = len(numbers) // getting length of an array
for i := 0; i < length/2; i++ {
temp := numbers[i]
numbers[i] = numbers[length - i - 1]
numbers[length - i - 1] = temp
}
return numbers
}
Output
[10 9 8 7 6 5 4 3 2 1]
