Dynamic planning 0-1 knapsack problem?description of the problem: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. Ask how to choose the items loaded into the backpack, so that the loadingIs the total value of the items in the backpack the most?? for an item, either put it in a backpack or do not install it. Therefore, the loading status o

Problemconsider a function which, for a given whole number N, returns the number of ones required when writing out all numbers between 0 and N. for example, F (13) = 6. notice that F (1) = 1. what is the next largest N such that F (n) = n? Algorithm idea: calculate the number of 1 in each number cyclically. If F (n) =

0/1 knapsack Problem's dynamic programming method solves, the predecessor's statement prepares, here does the work, but oneself realizes once according to the understanding, the main goal is to exercise the thinking and the programming ability, simultaneously, also is in order to enhance to the dynamic programming law mechanism understanding and grasps.A question worth mentioning is whether, when implemente

Idea: Preliminary view it is difficult to analyze the meaning of the expression at a glance, we might like to analyze the example, assuming that n = 5, the binary is represented as 101, then n-1 = 4, the binary is expressed as, 5 4 = 101 100 = 100 = 4! = 0, let's look at more examples below5 4 101 - 4 6 5 the 101 4 7 6 111 the 6 8 7 + 0111 0We will find that to make the expression equal to

Problem One solution:We know the number of factorial results at the end of the n is 0, which means that we do the multiplication of n from 1 when the number of 10we can decompose this, that is, the decomposition of the Genesis from 0 to N, and then multiply these by the number of 10? Actually, we just have to figure out how many of them are 5? because in these de

Set Description For a continuous integer from 1 to n, it can be divided into two subsets, and the number of each set are equal. For example, if n = 3, for {1, 2, 3}, it can be divided into two subsets. All their numbers are equal to: {3} and {1, 2 }, this is the only distribution (the switch set location is considered to be the same division scheme, so the total
