Expert Solution
Algorithm

Step 1: Define the function BetterChange() that takes three arguments namely the value, denominations and number of denominations.

Step 2: Initialize r with M.

Step 3: Iterate through the denominations in c

Step 4: Determine the quotient of the division r/c[j] and store it in the list i.

Step 5: Subtract the product quotient of the division (r/c[j]) and the denomination c[j] from r.

Step 6: Return the change stored in list i.

Step 7: Initialize M, c and d and invoke BetterChange().

Step 8: Display the change obtained for M.
