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

Given a group of items, each item has its own weight and value. within the defined total weight, how can we choose to make the total price of the item the highest.
Solution: value density PI/wi (PI indicates the value of the item I, and WI indicates the weight of the item I) greedy algorithm. This selection criterion is: select the item with the highest PI/wi value from the remaining item.

One, 0-1 knapsack problem Description:Known: Thieves in the shop to steal things, thieves only with a maximum load-bearing w backpack, the store has n goods, the first item of the weight is weight[i], the price is value[i].Limitations: each commodity only one, you can choose to take or not to take, can not be divided, can not only take a part of the product (so called 0
Question meaning:There are n villages in different coordinates and heights. Now we need to supply water to all the villages, as long as there is a road between the two villages. The distance between the water pipes is the Euclidean distance between the coordinates, the cost is the difference between the altitude and the distance. Now the scheme is required to minimize the cost to the distance. Obviously, this question requires an optimal rate spanning tree.0
Test instructions: There is a few gods and demons living on an island, and the number of gods and demons known, and now known that God is always telling the truth, demons are always telling lies, there are N questioning, asking a certain God or demon (identity unknown), the question is whether a god or a demon, according to their answer, ask if you can determine which is God andFor these problems, we only need to find that if the answer is a demon, then you can tell that the two are not the same
Lexical analysis of pl/0 language
First, the purpose of the experiment
Through the completion of lexical analysis procedures, understand the process of lexical analysis. Compile a read Word program, the lexical analysis of the pl/0 language, the input string form of the source program into a word symbol, that is, the basic reserved words, identifiers, constants, operators, the five major categories.

Problem:There are n items and a backpack with a capacity of V. The value of article I is c[i] and the weight is w[i]. The solution of which items are loaded into the backpack makes these items less than the total weight of the backpack and the maximum value.The problem is characterized by the following: Each item has only one piece, can choose to put or not to put. Use f[i][j] to indicate that the backpack current capacity is J, choose the maximum value when loading
