This is a repository of some simple Java scripts.
ShiftCipher is an implementation of Caesar cipher encryption.
By inputting a shift factor within the range from -26 to 25, a string can be encrypted. The code also demonstrates to use of ASCII character codes.
The characters are case-sensitive and are always retained. Numbers and special characters are not shifted.
With the inputs Hello and 3, the output Khoor is expected.
Given a list of coordinates and a starting location, calcuateRoute in
RoutePlanner orders the coordinates using the Nearest Neighbour Algorithm.
Suppose we have a list of coordinates: [(1.0,2.0),(3.0,3.0),(1.5,1.5)]. Let
the starting point be (0.0,0.0). Then, the route is calculateRoute(0.0,0.0) == [(1.5, 1.5), (1.0, 2.0), (3.0, 3.0)].
