DCEPC705 - Weird Points
Given N distinct points in a plane, a point (x1, y1) is said to be dominating another point (x2, y2) if x1>=x2 and y1>=y2.
The Dominance of a point is the absolute difference between 2 quantities – no. of points dominated by this point and no. of points not dominated by this point. (excluding itself)
A Weird point is the point whose Dominance value is greater than or equal to a threshold value ‘k’. Find the no. of such Weird Points among those N given points.
First line gives T, the no. of test cases.
Each test case consists of 2 integers in first line, N and K, as specified above.
Next N lines give the coordinates of N points in the plane. “Xi” and “Yi” are space separated.
Output T lines, each containing the required answer.
