Coding Problems

Question 1: Virtual Machine Scheduling

Q1: Given n virtual machines and their resource requirements, schedule them optimally on k hosts.

Solution (Java):

public int scheduleVMs(int[] vms, int k) {
    // Greedy approach: assign VMs to least loaded host
    PriorityQueue<Integer> hosts = new PriorityQueue<>();
    for (int i = 0; i < k; i++) {
        hosts.offer(0);
    }

    for (int vm : vms) {
        int minLoad = hosts.poll();
        hosts.offer(minLoad + vm);
    }

    int maxLoad = 0;
    while (!hosts.isEmpty()) {
        maxLoad = Math.max(maxLoad, hosts.poll());
    }
    return maxLoad;
}

Time Complexity: O(n log k)
