These two functions each return an array, which contains a sequence of intgers; if n = 0, then they return an empty array, and if n = 1 they return a single value, [1]. However, if n is larger, they return a sequence that counts through the nubmers 1 to n. In climbUp(), the sequence simply counts up; in climbDownUp(), it starts at n, counts down to 1, and then counts back up to n. For example, if n = 4, then annoying climbUp() will return [1,2,3,4], while annoying climbDownUp() will return [4,3,2,1,2,3,4].

Why should characters such as / \ " ' * ; - ? [ ] ( ) ~ ! $ { } < > # @ & | space, tab, and newline be avoided in file names?

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)
