Given a random non-negative number, you have to return the digits of this number within an array in reverse order.

TypeScript

const digitize = (n: number): number[] => {
    return String(n).split('').reverse().map(n => Number(n));
};

console.log(digitize(12345));

Go

package main

import "fmt"

func digitize(n int) []int {
    var result []int

    for n > 0 {
        result = append(result, n % 10)
        n /= 10
    }

    return result
}

func main() {
    fmt.Println(digitize(12345))
}

Python

def digitize(n):
    return [int(x) for x in str(n)[::-1]]

print(digitize(12345))

PHP

function digitize($n) {
    return array_map('intval', str_split(strrev((string)$n)));
}

print_r(digitize(12345));
