WebSince we need to maximize the objective function, Greedy approach can be used. Following steps are followed to find the solution: Step 1: Initialize sum = 0. Step 2: Select the root node, so its value will be added to sum, sum = 0+8 = 8. Step 3: The algorithm compares nodes at next level, selects the largest node which is 12, making the sum = 20.
