Create a function that returns an array of booleans from a given number by iterating through the number one digit at a time and appending true into the array if the digit is 1 and false otherwise.
integerBoolean("100101") ➞ [true, false, false, true, false, true]
integerBoolean("10") ➞ [true, false]
integerBoolean("001") ➞ [false, false, true]
Expect numbers with 0 and 1 only.
