### Java implementation knapsack algorithm (0-1 knapsack Problem)

0-1 questions about BackpacksKnapsack problem (knapsack Problem) is a np-complete problem of combinatorial Optimization. The problem can be described as: given a set of items, each item has its own weight and price, within a limited total weight, we choose how to make the total price of the item the Highest. The name of the problem comes from how to choose the most suitable item to be placed in a given backpack.This is the most basic

0-1 knapsack problem: given n items and a backpack. The weight of item I is WI, its value is VI, the capacity of the backpack is C. How do you choose which items are loaded into your backpack so that the total value of the items loaded into your backpack is greatest?When selecting items for backpack, there are only 2 options for each item I put in the backpack or not in the backpack. Item I cannot be loaded into the backpack multiple times, nor can I

### 0/1 knapsack problems (Dynamic Planning) and knapsack Planning
