An element of fewestCoins stores the fewest number of coins necessary for the amount of change corresponding to its index value.
For 29-cents using the set of coin types {1, 5, 10, 12, 25, 50}, determine the value of fewestCoins[29].
2. The binomial coefficient is the number of combinations/sets of picking k items form a bin containing n items. It is often written as:
=
a) What problems might arrive if we use the formula directly?
b) How might we write the binomial coefficient recursively?
(HINT: Split the sets into two groups as sets with a specific item and sets without the specific item.)
3. How can we write the dynamic programming algorithm for binomial coefficient?
3. For the 29-cent solution, what are the specific coins in the solution?
4. How much new information must we store to reconstruct the specific coins in a solution?
