B"Harry Potter has a difficult homework. Given a rectangular table, consisting of n xe2 x80 x89 xc3 x97 xe2 x80 x89m cells. Each cell of the table contains the integer. Harry knows how to use two spells: the first spell change the sign of the integers in the selected row, the second -- in the selected column. Harry's task is to make non-negative the sum of the numbers in each row and each column using these spells. Alone, the boy can not cope. Help the young magician! The first line contains two integers n and m (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n, xe2 x80 x89 m xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89100) -- the number of rows and the number of columns. Next n lines follow, each contains m integers: j-th integer in the i-th line is ai, xe2 x80 x89j (|ai, xe2 x80 x89j| xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89100), the number in the i-th row and j-th column of the table. The rows of the table numbered from 1 to n. The columns of the table numbered from 1 to m. In the first line print the number a -- the number of required applications of the first spell. Next print a space-separated integers -- the row numbers, you want to apply a spell. These row numbers must be distinct! In the second line print the number b -- the number of required applications of the second spell. Next print b space-separated integers -- the column numbers, you want to apply a spell. These column numbers must be distinct! If there are several solutions are allowed to print any of them."...
