If a 2-D SOM has a map of dimension w × d, and k input neurons, how many weights does it have?

Answer: w × d × k

You would have studied sorting algorithms in an early phase of your computing studies. They take unordered data, and order it. Sometimes is it good to have data in a random order, as when supplying (non-sequential) data to a neural net algorithm, or when shuffling cards for a game program. Write a procedure to shuffle a vector (e.g. Data vector[N]). Hint: one way to do this is to modify the basic framework of selection sort.
