Scan Line Polygon Filling Algorithm

Step1: Take points of polygon as input from user and store them in 2d array

Step2: Draw Polygon

Step3: Calculate 1/slope and put it to the 1d array

Step4: For each scan line

1. Find its intersection with the edges and store it in 1d array

2.Arrange the intersecting points in increasing order

3.Draw line b/w intersection points
