CodeChefOpen on judge ↗

Given N points on the plane, represented as (xi, yi) where both xi and yi are integers, you need to tell us the maximum number of distinct points that lie on a straight line. Your algorithm needs to be really efficient. Input The first line of the input contains the number of test cases T, atmost 10. Each of the next T lines contains the description of a single test case. Each test case begins
