# 15.8. SkyView - Part B¶

Part b. Write the SkyView method getAverage, which returns the average of the elements of the section of view with row indexes from startRow through endRow, inclusive, and column indexes from startCol through endCol, inclusive.

For example, if nightSky is a SkyView object where view contains the values shown below, the call nightSky.getAverage(1, 2, 0, 1) should return 0.8. (The average is (1.1 + 1.4 + 0.2 + 0.5) / 4, which equals 0.8). The section being averaged is indicated by the dark outline in the table below.
