Question

C
There is a road, the starting coordinate is 0, and the coordinatesof the line are given to draw a black line, for example, five linesegments for drawing black lines, (5, 6), (1, 2), (4, 8), (7 , 9)and (5, 8), as shown below

Output:Length of the black line on the road: 6
Maximum number of overlaps: 3
Maximum number of overlaps Length of black line: 2

The first row is a positive integer N, there are N line segments for drawing black lines.Then there are the integer values of the start point coordinates and the end point coordinates of the line segment of the black line.
