( 900 ) E Unsolvable PROGRAMMING math number theory 2100

Consider the following equation: Let's find all integer z ( z > 0) , for which this equation is unsolvable in positive integers. The phrase "unsolvable in positive integers" means that there are no such positive integers x and y ( x , y > 0) , for which the given above equation holds. Let's write out all such z in the increasing order: z 1 , z 2 , z 3 , and so on ( z i < z i + 1 ) . Your task is: given the number n , find the number z n . The first line contains a single integer n ( 1 ≤ n ≤ 40 ). Print a single integer — the number z n modulo 1000000007 (10 9 + 7) . It is guaranteed that the answer exists.
