Complete the function that takes a non-negative integer n as input, and returns a list of all the powers of 2 with the exponent ranging from 0 to n ( inclusive ).

TypeScript

function powersOfTwo(n: number): number[] {
    let acc: number[] = [];

    for (let i = 0; i <= n; i++) {
        acc.push(Math.pow(2, i));
    }

    return acc;
}

console.log(powersOfTwo(10));

Go

package main

import "fmt"

func powersOfTwo(n int) []int {
    acc := make([]int, n+1)

    for i := 0; i <= n; i++ {
      acc[i] = int(math.Pow(2, float64(i)))
    }

    return acc
}

func main() {
	fmt.Println(powersOfTwo(10))
}

Python

def powers_of_two(n):
    acc = []
    for i in range(n+1):
        acc.append(2**i)
    return acc

print(powers_of_two(10))

PHP

function powersOfTwo(int $n): array {
    $acc = [];

    for ($i = 0; $i <= $n; $i++) {
        $acc[] = pow(2, $i);
    }

    return $acc;
}

print_r(powersOfTwo(10));
