Lets consider a range of "K" binary digit numbers. In that range, we want to take a subset of those values which have (<="n" consecutive 0s) AND (<="n" consecutive 1s).
Then, we want to find the order of values in the resulting subset incrementally.
Also, we want to do the "un-ordering" of the values. i.e. find the value of the subset from the given order.
Note: The order must be found only by checking the subset value, and not by trying to iterate all values upto that value. This will be efficient for a large "K" range of digits.
Example:
K = 6
n <= 2 consecutive 0s AND 1s
