Let A be an array of n elements. We are given an array L of the same length such that L[i] is the label of the element A[i]. Assume that each label is an integer in the range 1, 2, ..., k, where k is a constant. We want to assign a unique rank in the range 1, 2, ...n to each element of A[i] according to the following rules: • If A[i] and A[j] have different labels, the element with smaller label should have the lower rank. If A[i] and A[j] have the same label, the element at lower index should have the lower rank. Design a parallel algorithm to compute the ranks and find its running time.

Usually, when we sniff packets, we are only interested certain types of packets. we can do that by setting filters in sniffing. scapy’s filter use the bpf (berkeley packet filter) syntax; you can find the bpf manual from the internet. set the following filters and demonstrate your sniffer program again (each filter should be set separately): (a) capture only the icmp packet. (b) capture any tcp packet that comes from a particular ip and with a destination port number 23. (c) capture packets comes from or to go to a particular subnet. you can pick any subnet, such as 128.230.0.0/16; you should not pick the subnet that your vm is attached to.
