Recursion java programming

How do I write a method that calculates the sum of the integers between 1 and n? I thought of using n + sum (n-1), but I need to use the recursive definition that the sum of 1 to n is the sum of 1 to n/2 plus the sum of (n/2+1) to n.

Recursion in Java

How do I write a method that calculates the sum of the integers between 1 and n? I thought of using n + sum (n-1), but I need to use the recursive definition that the sum of 1 to n is the sum of 1 to n/2 plus the sum of (n/2+1) to n. Assume that n is a positive integer.

Inventory - Java

Modify the Inventory Program by adding a button to the GUI that allows the user to move to the first item, the previous item, the next item, and the last item in the inventory. If the first item is displayed and the user clicks on the Previous button, the last item should display. If the last item is displayed and the user clicks on the Next button, the first item should display. Add a company logo (something about java) to the GUI using Java graphics classes.

Implement the function maxLoc(), which returns an interator pointing at the largest element in a list.

Implement the function maxLoc(), which returns an iterator pointing at the largest element in a list. //return an iterator pointing to the largest element //in the list. template list::iterator maxLoc(list& aList); Write a program taht tests maxLoc(), using the following declarations: string strArr[] = ("insert", "erase", "template", "list"); int strSize = sizeof(strArr)/sizeof(string); list strList(strArr, strArr+StrSize) The program should repeatedly call maxLoc(), output the largest value, and then delete the value, until the list is empty. I am attaching a .cpp file of the program. It is mostly complete but when I compile I don't seem ... click for more

You are working on a new computer game.

I need to answer the following 3 questions based on the below paragraph. I do NOT need any programming done, just answer the questions. (1) What type of problem are you investigating? (2) What steps would you take to analyze the problem? (3) What algorithms would be good to use and why? You are working on a new computer game. One of the implementation problems you are trying to solve is character path finding. The user should be able to select a character and left-click the mouse at a location to have the character move to that new location. Normal movement should send the character along a route with the shortest possible distance between locations. There are two special issues you... click for more
