Description:
Maximize count of intersecting line segments
Python3 program for the above approach ; Function to find the maximum number of intersecting line segments possible ; Stores pairs of line segments { X [ i ] , Y [ i ] ) ; Push { X [ i ] , Y [ i ] } into p ; Sort p in ascending order of points on X number line ; Stores the points on Y number line in descending order ; Insert the first Y pofrom p ; Binary search to find the lower bound of p [ i ] [ 1 ] ; If lower_bound doesn 't exist ; Insert p [ i ] [ 1 ] into the set ; Erase the next lower _bound from the set ; Insert p [ i ] [ 1 ] into the set ; Return the size of the set as the final result ; Driver Code ; Given Input ; Function call to find the maximum number of intersecting line segments
