Inlay the beads in the following way to get the maximum value 18. The type number of inlaid decorative beads is indicated in brackets:
2: (1) (2)
4: (2) (2)
4 skill 1 decorative beads, 4 skill 2 decorative beads W 1 ( 4 ) + W 2 ( 4 ) = 5 + 15 = 20 W_1(4) + W_2(4) = 5 + 15 = 20 W1(4)+W2(4)=5+15=20.
By reading the stem of the question, this question - difficulty medium and above: ⭐⭐⭐⭐
Type of investigation: Number Theory
Knowledge points: dynamic programming + enumeration
As it is a blank question, we only need to get one result. The result is an integer.
This problem is very interesting. For engineering men who love to play games, it will be a bit embarrassing if they can't do this kind of buff problem (kidding, the problem is still difficult! ~) first of all, they have to understand the problem stem. In fact, they need to understand it!
Let's take a look at the input example:
