( 14190 ) D Little Girl and Maximum XOR PROGRAMMING bitmasks dp greedy implementation math 1800

B'A little girl loves problems on bitwise operations very much. Here 's one of them. You are given two integers l and r. Let 's consider the values of for all pairs of integers a and b (l 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 x89r). Your task is to find the maximum value among all considered ones. Expression means applying bitwise excluding or operation to integers x and y. The given operation exists in all modern programming languages, for example, in languages C++ and Java it is represented as "^", in Pascal -- as "xor". The single line contains space-separated integers l and r (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89l xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89r xe2 x80 x89 xe2 x89 xa4 xe2 x80 x891018). Please, do not use the %lld specifier to read or write 64-bit integers in C++. It is preferred to use the cin, cout streams or the %I64d specifier. In a single line print a single integer -- the maximum value of for all pairs of integers a, b (l 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 x89r).'...
