The ternary expansion of a number is that number written in base 3. A number can have more than one ternary expansion. A ternary expansion is indicated with a subscript 3. For example, 1 = 13 = 0.222...3, and 0.875 = 0.212121...3. The Cantor set is defined as the real numbers between 0 and 1 inclusive that have a ternary expansion that does not contain a 1. If a number has more than one ternary expansion, it is enough for a single one to not contain a 1. For example, 0 = 0.000...3 and 1 = 0.222...3, so they are in the Cantor set. But 0.875 = 0.212121 . . .3 and this is its only ternary expansion, so it is not in the Cantor set. Your task is to determine whether a given number is in the Cantor set. Input The input consists of several test cases. Each test case consists of a single line containing a number x written in decimal notation, with 0 ≤ x ≤ 1, and having at most 6 digits after the decimal point. The last line of input is ‘END’. This is not a test case. Output For each test case, output ‘MEMBER’ if x is in the Cantor set, and ‘NON-MEMBER’ if x is not in the Cantor set. Sample Input 0 1 0.875 END Sample Output MEMBER MEMBER NON-MEMBER
