How to Iterate Over an Array in Reverse Order in Go - Step by Step Examples

How to Iterate Over an Array in Reverse Order in Go ?

Answer

To iterate over an array in Go in reverse order, you can use a for loop starting from the last index to the first index.

✐ Examples

1 Iterate Over Integer Array in Reverse with for Loop

In this example,

We create an integer array named numbers with some values.
We use a for loop starting from the last index to iterate over each element of the array in reverse order.

Go Program

package main

import "fmt"

func main() {
    numbers := []int{1, 2, 3, 4, 5}
    for i := len(numbers) - 1; i >= 0; i-- {
        fmt.Println(numbers[i])
    }
}

Output

2 Iterate Over String Array in Reverse with for Loop

In this example,

We create a string array named fruits with some values.
We use a for loop starting from the last index to iterate over each element of the array in reverse order.

Go Program

package main

import "fmt"

func main() {
    fruits := []string{"apple", "banana", "cherry"}
    for i := len(fruits) - 1; i >= 0; i-- {
        fmt.Println(fruits[i])
    }
}

Output

cherry
banana
apple
