http://acm.hdu.edu.cn/showproblem.php?pid=3547昨天比赛的题目;立方体顶点染色问题
本题是立方体顶点染色,polya计数的一部分:有公式直接套,(k^8+17*k^4+6*k^2)/24;其中k表示颜色数;由于题目是高精度,明显用Java可搞,但是悲催的是nbutOJ不支持直接ORZ。。。接下来开始了wa的悲催结果,,,,

Convert basic data types to strings using Java's String.valueOf() function In Java development, when we need to convert basic data types to strings, a common method is to use the valueOf() function of the String class. This function can accept parameters of basic data types and return the corresponding string representation. In this article, we will explore how to use the String.valueOf() function for basic data type conversions and provide some code examples to

1. Introduction The main design goal of float and double types is for scientific calculations and engineering calculations. They perform binary floating-point operations, which are carefully designed to provide fast approximate calculations with high accuracy over a wide range of values. However, they do not provide completely accurate results and should not be used where accurate results are required. However, business calculations often require accurate results, and BigDecimal comes in handy at this time. 2. Introduction to knowledge points 1. Overview 2. Construction methods 3. Addition, subtraction, multiplication and division operations 4. Description of source code 5. Summary 6. Refining exercises 3. Detailed explanation of knowledge points 1. Overview Why use BigDecimal? Code demonstration: packagecom.Test;import

Methods for comparing sizes: 1. Use the "compareTo()" method; 2. Use the "equals()" method; 3. Use the overloaded version of the "compareTo()" method; 4. Use the chain of the "compareTo()" method Call etc.

Java document interpretation: Usage analysis of the currentTimeMillis() method of the System class, specific code examples are required. In Java programming, the System class is a very important class, which encapsulates some properties and operations related to the system. Among them, the currentTimeMillis method is a very commonly used method in the System class. This article will explain the method in detail and provide code examples. 1. Overview of currentTimeMillis method

Use Java's Boolean.valueOf() function to convert a string to a Boolean value. In Java programming, you often encounter situations where you need to convert a string to a Boolean value. Java provides a convenient way to achieve this requirement, using the Boolean.valueOf() function. This function can convert a Boolean value represented by a string into the corresponding Boolean type. Let's take a closer look at the usage of Boolean.valueOf(). Given a string, we

1. Explain that an exception occurs during division. java.lang.ArithmeticException:Non-terminatingdecimalexpansion;noexactrepresentabledecimalresult When dividing by the divide method of BigDecimal, if there is no integer division and a recurring decimal occurs, an exception will be thrown: java.lang.ArithmeticException:Non-terminatingdecimalexpansion;noexactrepresentabledecimalresult.

1. The description takes using BigDecimal to format currency and percentage as an example. First, create a BigDecimal object, perform BigDecimal arithmetic operations, and establish currency and percentage formatted references respectively. Finally, use the BigDecimal object as a parameter of the format() method to output its formatted currency value and percentage. 2. Instance NumberFormatcurrency=NumberFormat.getCurrencyInstance();//Create currency formatting reference NumberFormatpercent=NumberFormat.getPercentIns
