( 22101 ) A Equation PROGRAMMING brute force math 800

B"Let's call a positive integer composite if it has at least one divisor other than 1 and itself. For example: You are given a positive integer n . Find two composite integers a,b such that a-b=n . It can be proven that solution always exists. The input contains one integer n ( 1 <= q n <= q 10^7 ): the given integer. Print two composite integers a,b ( 2 <= q a, b <= q 10^9, a-b=n ). It can be proven, that solution always exists. If there are several possible solutions, you can print any. "...
