Design an algorithm to find the weighted average of four test scores. The four test scores and their respective weights are given in the following format: testscore1 weight1 ... For example, the sample data is as follows: 75 0.20 95 0.35 85 0.15 65 0.30 The user is supposed to enter the data and press a Calculate button. The program must display the weighted average.

The option enables you to modify a slide element in most presentation applications.

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should not be added to the list). these values entered by the user are added to a list we call 'initial_list'. then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. finally, inside print out all of the values in the new list. for example: input: enter value to be added to list: a enter value to be added to list: b enter value to be added to list: c enter value to be added to list: exit output: a b c a b c a b c note how 'exit' is not added to the list. also, your program needs to be able to handle any variation of 'exit' such as 'exit', 'exit' etc. and treat them all as 'exit'.
