( 2919 ) E Team Work PROGRAMMING combinatorics dp math 2400

B'You have a team of N people. For a particular task, you can pick any non-empty subset of people. The cost of having x people for the task is xk. Output the sum of costs over all non-empty subsets of people. Only line of input contains two integers N (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89N xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89109) representing total number of people and k (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89k xe2 x80 x89 xe2 x89 xa4 xe2 x80 x895000). Output the sum of costs for all non empty subsets modulo 109 xe2 x80 x89+ xe2 x80 x897. In the first example, there is only one non-empty subset {1} with cost 11 xe2 x80 x89= xe2 x80 x891. In the second example, there are seven non-empty subsets. - {1} with cost 12 xe2 x80 x89= xe2 x80 x891 - {2} with cost 12 xe2 x80 x89= xe2 x80 x891 - {1, xe2 x80 x892} with cost 22 xe2 x80 x89= xe2 x80 x894 - {3} with cost 12 xe2 x80 x89= xe2 x80 x891 - {1, xe2 x80 x893} with cost 22 xe2 x80 x89= xe2 x80 x894 - {2, xe2 x80 x893} with cost 22 xe2 x80 x89= xe2 x80 x894 - {1, xe2 x80 x892, xe2 x80 x893} with cost 32 xe2 x80 x89= xe2 x80 x899 The total cost is 1 xe2 x80 x89+ xe2 x80 x891 xe2 x80 x89+ xe2 x80 x894 xe2 x80 x89+ xe2 x80 x891 xe2 x80 x89+ xe2 x80 x894 xe2 x80 x89+ xe2 x80 x894 xe2 x80 x89+ xe2 x80 x899 xe2 x80 x89= xe2 x80 x8924.
