Question 2: {CLO2,3 WASA has captured an image of a distant area of planet earth where either land or water is visible. They want to (Marks; 10) count the number of islands in the captured image. An II expen in team NASA has convented that image into a nxn binary matrix such that 0 represents earth and 1 represents water. Your task is to find the total number of islands in the image given the nxn matrix. For example Griven the following matrix, your answer must be three as there are three isolated land regions. The shud in in this exampie. Hint. This problem can be solved by considering this matrix as a graph where each cell is a vertex and adjacent cells are neighbors of that vertex. Write a C+ function that takes a nxn binary matrix as parameter and retum the numbet of islands. Less efficient implementation will be awarded less credit
