Question
Suppose you are to make change for the amount 1234 with the
smallest possible number of coins. The coin values you have
available to you are 1, 17, and 29. In implementing a recursive
solution mincoins( n ), what three values of n would be used for
the three recursive calls of mincoins()?
Smallest:
Next:
Largest:
This straight recursive implementation would have exponential
runtime because results are computed repeatedly. One
speedup technique would be to make a table and store
intermediate results when they are computed, so they don't
need to be computed again.
What is this technique called?
Another speedup technique involves computing mincoins(1),
mincoins(2),
mincoins(1234). What is this technique
