The binary weight of a positive integer is the number of 1's in its binary representation. For example, the decimal number 1 has a binary weight of 1, and the decimal number 1717 (which is 11010110101 in binary) has a binary weight of 7.
Given a positive integer N, return the smallest integer greater than N that has the same binary weight as N.
|-||The result is guaranteed to fit in a signed 32-bit integer.|
|-||N will be between 1 and 1,000,000,000, inclusive.|
