Method 1: Use Integer.toBinaryString(a) where a is an Int. This method is from the Java platform and can be used in Kotlin. Find more about this method at https://docs.oracle.com/javase/7/docs/api/java/lang/Integer.html#toBinaryString(int)

Note: This method works for both positive and negative integers.

Method 2: Use a.toString(2) where a is an Int, 2 is the radix Note: This method only works for positive integers.
