The janitor of a high school is extremely efficient. By the end of each day, all of the school's waste is in plastic bags weighing between 1.01 pounds and 3.00 pounds. All plastic bags are then taken to the trash bins outside. One trip is described as selecting a number of bags which together do not weigh more than 3.00 pounds, dumping them in the outside trash can and returning to the school. Given the number of plastic bags n, and the weights of each bag, determine the minimum number of trips the janitor has to make. For example, given n = 6 plastic bags weighing weight = [1.01, 1.99, 2.5, 1.5, 1.01], the janitor can carry all of the trash out in 3 trips: [1.01 + 1.99 , 2.5, 1.5 + 1.01]. Write a java program to implement efficient janitor and explain the time complexity of your code.

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)
