3. How might the heap implementation of priority
queues be used to solve the following problems?
How do your answers change when the inputs are
sorted?
a. Construct a Huffman code (such codes are dis-
cussed in most books on information theory and
many books on data structures).
b. Compute the sum of a large set of floating point
numbers.
c. Find the 1000 largest of ten million numbers
stored on a magnetic tape.
d. Merge many small sorted files into one large
sorted file (this problem arises in implementing a
disk-based Mergesort program).
