Given points on a 2D plane, judge whether there're three points that locate on the same line. 输入格式 The number of test cases $ T $ ($ 1 \leq T \leq 10 $) appears in the first line of input. Each test case begins with the number of points $ N $ ($ 1 \leq N \leq 100 $). The following $ N $ lines describe the coordinates $ (x i, y i) $ of each point, in accuracy of at most 3 decimals. Coordinates are ranged in $ [-10^4, 10^4] $. 输出格式 For each test case, output $ Yes $ if there're three points located on the same line, otherwise output $ No $. 输入样例 2 3 0.0 0.0 1.0 1.0 2.0 2.0 3 0.001 -2.000 3.333 4.444 1.010 2.528 输出样例 Yes No
