| # Codility challenge for base -2 with the least significative bit at the left. | |
| # | |
| # In base -2 integers are represented by sequences of bits in the following way. | |
| # Bits are ordered from the least to the most significant. Sequence B of N bits | |
| # represents the number: sum(B[i] * (-2)^i for i = 0..N-1). The empty sequence represents 0. | |
| # Note that such representation is suitable for both positive and negative numbers. | |
| # NOTE: Remember negative division returns the floor. http://python-history.blogspot.mx/2010/08/why-pythons-integer-division-floors.html | |
