Questions:Given n kinds of goods and a backpack. The weight of item I is WI, its value is VI, the capacity of the backpack is C.For an item that is only loaded or not installed, the problem is called a 0-1 knapsack problem.Ask how to choose the items in your backpack so that the total value of the items loaded into the backpack is the greatest.Analysis:n Kinds of Goods:

Because the data range is 20, the direct enumeration is 2 ^ 20 and does not time out. Simply find the combination. In N, take 1 and 2 .... N number.

0-1 knapsack problem0-1 knapsack Problem Descriptive narrativeThere was a thief who stole a store and found that there were n items, and the item I was worth is vI, and the weight was WI. Ifboth V I and Wi are integers. He hopes to take away the more valuable the better, but his backpack is more than just to fit the W-pound thing. W is an integer.What kind of thi

Dynamic Planning is the abstraction of a method for changing the space for time. The key is to discover sub-problems and record their results. Then use these results to reduce the computational workload.For example, 01. /* A traveler has a backpack that can use up to M kilograms and now has n items,Their weights are W1, W2,..., Wn,Their values are P1, P2,..., Pn.If each itemOnly oneAsk the traveler to obtain the maximum total value.Input Format:M, nW1, p1W2, p2......Output Format:X*/ The maximum

It's a little piece of cake in the neighborhood today: "How many times did 1 appear in 0~400?" ”。Side dishes to see the majority of users to the algorithm is based on string processing, the idea is roughly: stitching all the numbers into a string, and then processing the string, and then get the number of occurrences. For example, the following code:1 /**2 * User
