» The following array of integers are to be
sorted into ascending order:
42108612
If selection sort is chosen to sort this array,
write the contents of the array each time that
the sort algorithm changes it. How many
comparison operations and how many swaps
are performed in the sorting?
„It is suspected that out of a set of 64 50p
coins one of the coins is fake (i.e., lighter in
weight than a genuine coin). With one
weighing scale
i give a detailed explanation on how you
would go about determining the fake coin.
What is the minimum number of times you
need to use the scales to weigh the coins
before identifying the fake
coin?
ii.
b) Write a recursive method that returns the
value of N! (N factorial). Explain why you
would not normally use recursion to solve
this problem.
