Uluthando needs your help to plant some trees. He can give you three parameters of the land: - width of the land w - length of the land l - gap between the trees g You have to create an algorithm to return the number of trees which can be planted on the edges of the given land in a symmetrical layout shown below (unsymmetrical gap = x, tree = o, gap = -): w=3, l=3, g=1 plantTrees(w, l, g) ➞ 4 o - o - - o - o // Uluthando can plant 4 trees. w=3, l=3, g=3 plantTrees(w, l, g) ➞ 2 o - - - - - - o // Uluthando can plant 2 trees. If the layout is not symmetrical, you have to return 0: w=3, l=3, g=2 plantTrees(w, l, g) ➞ 0 o - - x o x x x // Planting 2 trees mean the gap of two trees will be greater than 2. o - - x o o - - // Planting 3 trees mean the gap of two trees will be less than 2. Another Example for better understanding: w=3, l=3, g=0 plantTrees(w, l, g) ➞ 8 o o o o o o o o // Uluthando can plant 8 trees. ​
