Title Description

Input a series of square wave signals , Find the longest completely continuous alternating square wave signal , And output it , If there are alternating square wave signals of the same length , Just output any , The square wave signal is used for high level 1 identification , In the low position 0 identification , Pictured ：

explain ：

1. A complete signal must be in 0 Start with 0 ending , namely 010 It's a complete signal , but 101,1010,0101 No
2. The input string of square wave signals is composed of one or more complete signals
3. There may be... Between two adjacent signals 0 One or more low positions , Such as 0110010,011000010
4. There can be consecutive high bits in the same signal , Such as 01110101011110001010, front 14 A bit is a signal with consecutive high bits
5. Completely continuous alternating square wave refers to 10 alternate , Such as
