C# code debugging.
Debug the C# code (solution.doc) which allows user to delete any existing node whose child nodes are internal nodes. Line code is 160 (2 or 3 lines of code). I get stock overflow when I try to remove Node 19. Can you take a look?
Also, write something about the error and how did you fix it. Thanks.

The assignment would consist of creating a program in VPython that will place eight 1-nC charges at the following coordinates (in meters): <0,0,0>, <0,0,1>, <0,1,0>, <0,1,1>, <1,0,0>, <1,0,1>, <1,1,0>, and <1,1,1>. It will then ask for the x, y, and z coordinates of a point in space. The program should then draw arrows (of the same length) from each charge toward <x,y,z>. Finally, the program should output the total electric field at <x,y,z>.
