Suppose you are having an array of n integer. All the elements in the array are unique
except one element. That one special element in array is repeating in array in order of power two(means even repetition)
example - 1 2 3 4 5 6 5 7 8
all element in this array are unique except 5.. and 5 is repeating 2 times (power of 2).
we need an algo to find this special element in array

what is the condition, is it "power of two" or "even"? If you notice, not every even number can be "power of two". :D
