A function in JavaScript that gets a number as a parameter and returns back an array containing powers of two that sum of all equals to the passed number

deconstructPowersOfTwo.js

/**
 * @param {number} num - it's a number in radix 10 that indicates summation of power of 2 numbers
 * @returns an array containing power of 2 numbers that sum of all is equal to num
 */
