The Eco-Marathon is an annual competition sponsored by Shell Oil, in which participants build special vehicles to achieve the highest possible fuel efficiency. The Eco-Marathon is held around the world with events in the United Kingdom, Finland, France, Holland, Japan, and the United States. A world record was set in Eco-Marathon by a French team in 2003 called Microjoule with a performance of 10,705 miles per gallon. The Microjoule runs on ethanol. If the cars are given 100 grams of ethanol (specific gravity = 0.789) and drive until the fuel runs out, how far did the Microjoule drive in kilometers?

Write a function to find the factors of an input number. The function should have one input n and a single output of a vector whose entries are the factors of n. The only built in functions you are allowed to use are mod or rem (I would prefer mod). Demonstrate that your function works as expected.

When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain less than 20 integers. Ex: If the input is 5 30 50 10 70 65, the output is:20 40 0 60 55For coding simplicity, follow every output value by a space, including the last one.
