Defend the use of on-line communities for user assistance. Ensure your argument is well-rounded by pointing out both the weaknesses and strengths.
What will be an ideal response?
Google Groups, Yahoo Groups, Usenet Newsgroups and others are both a collaboration method and an on-line user assistance source. They are ideal for finding out information from peers who have been there before. One popular application has been for people fighting a disease, even a rare disease, to share lessons learned and facts about treatment and cures. The danger has to be privacy issues. Also, there can be a rather high frequency of discussions that one would have to sift through to find the nugget of information desired. Also, persons needing a repair or technique related to a technology device or appliance may go to the on-line community for suggestions and ideas. Overall this author would argue the good outweighs the bad in connecting people to solutions.

A common example of a recursive formula is one to compute the sum of the first n integers, 1 + 2 + 3 + … + n. The recursive formula can be expressed as 1+2+3+…+n=n+(1+2+3+…+(n – 1)) Write a static method that implements this recursive formula to compute the sum of the first n integers. Place the method in a test program that allows the user to enter the values of n until signaling an end to execution. Your method definition should not use a loop to add the first n integers.
This Project is also very easy to write as a recursive algorithm. The base case returns one and any other case adds the number passed to it to the number returned by a recursive call with the number passed to it reduced by one. Note that the program loops until the user enters a positive integer since the progression is defined only for positive integers.
