Apply the rules in writing identifiers when representing your input data, calculated data and output data. 1. Draw a flowchart that represents the logic of a program that allows the user to input the speed (kilometers per hour) and the distance (in kilometers) travelled by certain biker to reach a destination. The program should calculate the time (in hours) spent to reach the destination, assuming that his/her speed was constant. It should print the time it took for the biker to reach his/her destination. (Given: distance = speed X time)1. (*) Find regular expressions to define the following tokens: string constants, boolean constants, hexadecimal numbers. 2.

He can only carry out a certain amount of stuff before it gets too heavy. In addition, Jesse can only make one trip in and out of the store before the cops arrive, so he wants to be sure to get the most value out of the stuff he takes. Input for the program will be as below. The first line will contain how much Jesse can carry. This line is followed by a single item per line. Each of these lines will contain the name of the item, the number of items available, each individual item’s weight and its value. There will be up to 10 different items. Output the number of each item type he should take to maximize his value as well as the max value.
