Problem Statement

Southern China is suffering from a heavily snowy winter. The heavy snow even causes the closure of an important highway connecting southern and northern China. You've got several reports containing the start and end points of highway segments covered by heavy snow. Given those reports as two int[]s startPoints and endPoints, you are to return the total length of highway segments covered by snow. Note that the reported segments may overlap.

Definition

Class:: SnowyWinter
Method:: snowyHighwayLength
Parameters:: int[], int[]
Returns:: int
Method signature:: int snowyHighwayLength(int[] startPoints, int[] endPoints)
(be sure your method is public)

Constraints

startPoints will contain between 1 and 50 elements, inclusive.
endPoints will contain the same number of elements as startPoints.
Each element of startPoints and endPoints will be between 0 and 10000, inclusive.
The i-th element of startPoints will be smaller than the corresponding element in endPoints.
