Create a sequential list with some data elements, and finish such operations as initialization, insertion, deletion etc. all operations should be implemented as independent functions, which can be called by the main function. (1) create a sequential list with data elements of 21, 18, 30, 75, 42, 56, and output all the elements (2) get the 3rd element of the list, and output the value; (3) insert 67 into the list at positon 3, and then output all the elements in the list;

Suppose you have 9 coins and one of them is heavier than others. other 8 coins weight equally. you are also given a balance. develop and algorithm to determine the heavy coin using only two measurements with the of the balance. clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms

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.)

Can someone work out the answer as it comes up in one of my computer science exams and i don't understand the cryptovariables
