The last one was quite something. I needed a lot of extra reading to complete it.

One idea for "bit operations", take a random example i = "0..0100101": Step1: right shift i by 1 -> "0..0010010" Step2 : bitwise OR -> "0..0110111" and take this as new i Step3: repeat Step 1 and 2 until all bits after highest "1" bit are all "1", i.e., i should be "0..0111111" Step4 : right shift i by 1 -> "0..0011111" and flip all bits (I'll call this j) Now we have i: 0..0111111 j: 1..1100000 It should be clear by now how to get the highest "1" bit. reference: https://habr.com/ru/post/93172/

Is this allowed? How do you repeat without a loop or without exceeding the size of the number? My single line solution below works but it fails verification because I am using things I am not allowed apparently. 

        return Integer.valueOf(1 << (Integer.toBinaryString(number).length() - 1));
