An organization is assigned a Class-C network 200.120.80.0 and wants to form subnets for its three departments: D1 (60 hosts), D2 (90 hosts), and D3 (90 hosts). Describe a possible arrangement of subnets (i. e., give the network address and the subnet mask of each subnet) to make this possible. Note that a department may be assigned multiple subnets; subnets may have different sizes and they shall not overlap.

Suppose you have 9 coins and one of them is heavier than others. other 8 coins weight equally. you are also given a balance. develop and algorithm to determine the heavy coin using only two measurements with the of the balance. clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
