8.12 (Simulation: The Tortoise and the Hare) In this exercise, you’ll re-create the classic race of the tortoise and the hare. You’ll use random-number generation to develop a simulation of this memorable event. Our contenders begin the race at “square 1” of 70 squares. Each square represents a possible position along the race course. The finish line is at square 70. The first contender to reach or pass square 70 is rewarded with a pail of fresh carrots and lettuce. The course weaves its way up the side of a slippery mountain, so occasionally the contenders lose ground. There is a clock that ticks once per second. With each tick of the clock, your program should use function moveTortoise and moveHare to adjust the position of the animals according to the rules in Fig. 8.18 (view your book for the rules in the table). These functions should use pointer-based pass-by-reference to modify the position of the tortoise and the hare. Use variables to keep track of the positions of the…
5.18 Name Lookup The starter code creates a list of first names and a corresponding list of last names. The user is able to enter a first name to look up, which is stored in userInput. Loop through the list of names to find first names which match the user input, and output the corresponding first and last names. For example, if the user searches for 'Amanda', then the program outputs: The following matches were found: Amanda Gates If the user searches for 'Steve', then the program outputs: The following matches were found: Steve Moore Steve Jones If no match is found, then the program outputs: The following matches were found: (none) Hint: use the zip function to simultaneously iterate through the firstName list and lastName list. firstName = ['Joe', 'Amy', 'Sarah', 'Steve', 'Amanda', 'Steve']lastName = ['Johnson', 'Smith', 'Jenkins', 'Moore', 'Gates', 'Jones']

3.27 (World Population Growth) World population has grown considerably over the centuries. Continued growth could eventually challenge the limits of breathable air, drinkable water, arable land and other limited resources. There’s evidence that growth has been slowing in recent years and that world population could peak some time this century, then start to decline. For this exercise, research world population growth issues. This is a controversial topic, so be sure to investigate various viewpoints. Get estimates for the current world population and its growth rate. Write a script that calculates world population growth each year for the next 100 years, using the simplifying assumption that the current growth rate will stay constant . Print the results in a table. The first column should display the year from 1 to 100. The second column should display the anticipated world population at the end of that year. The third column should display the numerical increase in the world…
