The main topic: Your phone Address book has n contacts, m groups, which, some of the contacts in multiple groups. Your task is to delete some of the contacts in some groups so that each contact is in only one group and the fewest number of people in the group. Find out the number of people in the group with the largest number.Title Analysis: Required is the smallest maximum, two-minute enumeration of this minimum maximum number of x. Increase the source point S and the meeting point T, an arc fr
Title: Give a graph with weights to find a minimum loop through the start S and end point T.Problem Analysis: Establish network, with S as the source point, T is the meeting point, and the capacity of each edge is 1, the unit cost is the edge weight value. To find the minimum cost flow, the minimum cost of augmentation two times is the answer.The code is as follows:# include UVA-10806 Dijkstra, Dijkstra. (Minimum cost

Problem descriptionnetwork flow is a well-known difficult problem for acmers. given a graph, your task is to find out the maximum flow for the weighted directed graph. inputthe first line of input contains an integer T, denoting the number of test cases.
For each test case, the first line contains two integers n and M, denoting the number

The input stream, the output stream is exactly how to distinguish, in writing code often encounter problems, or often confusing to find two of the relationship between streams. Through today's study to make a note, but also to provide everyone to learn, at the same time ask me questions.
The book saysInput stream: Data can only be read from and cannot be written to.Output stream: Data can only be written to it and cannot be read from.
So I have a question, what the hell is this stream?

1. if statement:
The if statement is used to test a condition. if the condition is true, we run a statement (called the if-block). Otherwise, we will process another statement (called the else-block ). The else clause is optional.
You can also use the elif statement, which combines two associated if else-if else statements into an if elif else statement to s
