Recall that a loop invariant is used to prove that a loop is correct (which in turn helpsto prove that an algorithm is correct).1. Write pseudocode that uses a while loop to find the second largest element in an unsorted array. Theinput to your algorithm should be an unsorted arrayAof real values. The psuedocode should use thevariable namecurguessto store the current guess of the second largest value, andcurmaxto storethe current max ofA.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e. g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
