Problem 1286
Verifying CRC polynomial
Time Limit: 1000ms
Memory Limit: 65536kb Description
Cyclic redundancy check(CRC) is an error-detecting code commonly used many fields. A common misconception is that the “best” CRC polynomials are derived from either an irreducible polynomial or an irreducible polynomial times the factor (1 + If you don’t know what I am talking about, please read the web page in above hyperlink. Given a polynomial of 33 or less bits, please check if it satisfies above condition. Input
The input consists of multiple test cases. Each test case contains a single string of length The input ends with “ Output
For each test case, output “ Sample Input
