B"You are given an integer m, and a list of n distinct integers between 0 and m xe2 x80 x89- xe2 x80 x891. You would like to construct a sequence satisfying the properties: Construct any sequence satisfying the properties above. The first line of input contains two integers n and m (0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89< xe2 x80 x89m xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89200 xe2 x80 x89000) -- the number of forbidden prefix products and the modulus. If n is non-zero, the next line of input contains n distinct integers between 0 and m xe2 x80 x89- xe2 x80 x891, the forbidden prefix products. If n is zero, this line doesn't exist. On the first line, print the number k, denoting the length of your sequence. On the second line, print k space separated integers, denoting your sequence. For the first case, the prefix products of this sequence modulo m are [1, xe2 x80 x892, xe2 x80 x893, xe2 x80 x894, xe2 x80 x890]. For the second case, the prefix products of this sequence modulo m are [3, xe2 x80 x897, xe2 x80 x894, xe2 x80 x896, xe2 x80 x898, xe2 x80 x890]. "...
