Pro.ID22120 TitleAlice and Bob Title链接http://10.20.2.8/oj/exercise/problem?problem_id=22120 AC0 Submit5 Ratio0.00% 时间&空间限制描述Alice is a beautiful and clever girl. Bob would like to play with Alice. One day, Alice got a very big rectangle and wanted to divide it into small square pieces. Now comes a problem: if all pieces of small squares are of the same size, how big could the squares be? To Alice, it’s easy to solve the problem. However, she was very busy, so she asked Bob to help her. You know Alice is such a lovely girl and of course Bob won’t refuse her request. But Bob is not so smart and he is especially weak in math. So he turns to you — a genius at programming. Alice will inform Bob the length and width of the big rectangle, and Bob have to tell her the longest length for the small square. All of these numbers are in their binary representations. 输入The first line of the input is a positive integer. This is the number of the test cases followed. Each test case contains two integer L and W in their binary representation which tells you the length and width of the very big rectangle ( 0 < L, W < 21000 ). There may be one or several spaces between these integers. 输出Description Alice is a beautiful and clever girl. Bob would like to play with Alice.

Input The first line of the input is a positive integer. This is the number of the test cases followed. Each test case contains two integer L and W in their binary representation which tells you the length and width of the very big rectangle ( 0 < L, W < 21000 ). There may be one or several spaces between these integers. Output The output of the program should consist of one line of output for each test case. The output of each test case only contains the longest length for the small squares in its binary representation. No any redundant spaces are needed. Sample Input 2
