A cool number is a non-negative integer that contains at least three consecutive ones or three consecutive zeroes in its binary representation (without leading zeroes). For example, 8 (1000 binary) and 15 (1111 binary) are cool numbers, but 27 (11011 binary) is not.
Return the number of cool numbers between lowerBound and upperBound, inclusive.
|-||upperBound will be between 0 and 2147483647, inclusive.|
|-||lowerBound will be between 0 and upperBound, inclusive.|
