Well Reversing the array i.e. reversing the sequence of words in an
array can be done as below :
1. Reverse the whole string i.e. reverse the sequence of alphabets :
dlrow olleh
2. Reverse the words independently now i..e apply the step 1 on sub
arrays that are enclosed between 2 blank spaces.:

Buddy my proposed algo is linear one, since you do the xor operation
(d+1)n times, where d is the number of bits in N.
