( 2439 ) C Hack it! PROGRAMMING binary search constructive algorithms math 2800

B"Little X has met the following problem recently. Let's define f(x) as the sum of digits in decimal representation of number x (for example, f(1234) xe2 x80 x89= xe2 x80 x891 xe2 x80 x89+ xe2 x80 x892 xe2 x80 x89+ xe2 x80 x893 xe2 x80 x89+ xe2 x80 x894). You are to calculate Of course Little X has solved this problem quickly, has locked it, and then has tried to hack others. He has seen the following C++ code: The first line contains a single integer a (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89a xe2 x80 x89 xe2 x89 xa4 xe2 x80 x891018). Print two integers: l, xe2 x80 x89r (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89l xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89r xe2 x80 x89< xe2 x80 x8910200) -- the required test data. Leading zeros aren't allowed. It's guaranteed that the solution exists."...
