Maximize the number by rearranging bits | An efficient python3 program to find minimum number formed by bits of a given number ..
Returns maximum number formed by bits of a given number ..
_popcnt32 ( a ) gives number of 1 's  present in binary representation of a..
If all 32 bits are set ..
Find a number witn n least significant set bits ..
Now shift result by 32 - n.
