Task description:

You are required to write a LoadBalancer class. The class has 2 public methods. The first – the constructor – takes two arguments. The first argument is a list of host instances that should be load balanced. The second argument is the variant of load balancing algorithm to be used.

There are two variants: the first will simply pass the requests sequentially in rotation to each of the hosts in the list. The second one will either take the first host that has a load under 0.75 or if all hosts in the list are above 0.75, it will take the one with the lowest load.

The second method is called handleRequest(Request $request) and will load balance the request according to the variant passed on construction.

You can assume that the host instances class has the following API: public int getLoad() public void handleRequest(Request $request)

Files: LoadBalancer - requested class.

testLoadBalancer - CLI script written to test the solution. To test different variants and hosts amounts, simply change the respective constants.

Host, Request - classess used by testing script to create object mocks.
