B"The year 2015 is almost over. Limak is a little polar bear. He has recently learnt about the binary system. He noticed that the passing year has exactly one zero in its representation in the binary system -- 201510 xe2 x80 x89= xe2 x80 x89111110111112. Note that he doesn't care about the number of zeros in the decimal representation. Limak chose some interval of years. He is going to count all years from this interval that have exactly one zero in the binary representation. Can you do it faster? Assume that all positive integers are always written without leading zeros. The only line of the input contains two integers a and b (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89a xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89b xe2 x80 x89 xe2 x89 xa4 xe2 x80 x891018) -- the first year and the last year in Limak's interval respectively. Print one integer xe2 x80 x93 the number of years Limak will count in his chosen interval. In the first sample Limak's interval contains numbers 510 xe2 x80 x89= xe2 x80 x891012, 610 xe2 x80 x89= xe2 x80 x891102, 710 xe2 x80 x89= xe2 x80 x891112, 810 xe2 x80 x89= xe2 x80 x8910002, 910 xe2 x80 x89= xe2 x80 x8910012 and 1010 xe2 x80 x89= xe2 x80 x8910102. Two of them (1012 and 1102) have the described property."...
