由于给定的信息中,标题和描述内容重复,且标签为空,没有提供具体的文件内容,所以无法进行深入的知识点分析。但是,从标题中的关键词“卢布”,“区块链”,“stukan2021”可以推测,本文档可能与俄罗斯货币卢布和区块链技术在2021年的某个事件或者状态有关。Stukan可能是一个拼写错误或者专有名词,但由于信息有限,无法确定其含义。 知识点解释如下: 1. 卢布(Ruble):是俄罗斯联邦的官方货币。它由俄罗斯联邦中央银行发行,发行机构为俄罗斯中央银行。货币代码为RUB。卢布的发行历史可以追溯到18世纪,它的使用与俄罗斯经济政策和国际经济形势紧密相关。 2. 区块链(Blockchain):区块链是一种分布式数据库,通过密码学保证传输和访问的安全,实现数据的透明性、不可篡改性和去中心化。区块链最著名的应用是作为比特币等加密货币的底层技术。区块链技术还被认为可以应用于金融、医疗、供应链、房地产等多个行业,以提高数据安全性和透明度。 3. 加密货币(Cryptocurrency):加密货币是使用加密技术的数字货币。比特币是第一个也是最著名的加密货币,它不依赖于中央银行,而通过去中心化的交易和记录账本(区块链)来维持运作。除了比特币,还有很多其他类型的加密货币,例如以太坊、瑞波币等。 4. 金融技术(FinTech):金融技术是指采用科技手段和创新思维在金融服务领域中所进行的各类业务模式创新,它涵盖了移动支付、在线银行、众筹、加密货币等多种新兴金融服务。FinTech的发展正不断改变传统的金融行业运作模式,提高服务效率,降低成本,促进金融包容性。 5. 俄罗斯经济与区块链:俄罗斯政府已经表明支持区块链技术的开发与应用,并对加密货币持有谨慎态度。近年来,俄罗斯有部分机构和企业在尝试利用区块链技术来增强其金融服务的透明度和效率,也有将卢布数字化的构想被提出。然而,由于加密货币的匿名性和波动性,俄罗斯政府对其监管持谨慎态度,甚至在某些时期禁止加密货币交易。 6. 2021年相关的事件或状态:由于缺乏具体的信息,无法确定2021年具体发生了哪些与卢布和区块链相关的事件。然而,2021年对于区块链和加密货币来说是动荡的一年,整个市场经历了从高点到低点的剧烈波动,同时各国政府对于加密货币的监管政策也在不断演变,这些变化可能对卢布和俄罗斯的区块链应用场景产生了影响。 由于上述文件标题中的“stukan2021”可能存在误拼或指向特定内容,无法提供具体的知识点。若需要更深入的分析,建议提供更多的文档内容,以便给出更准确的知识点解析。

用c++解决For example, if you want to exchange 100 US Dollars into Russian Rubles at the exchange point, where the exchange rate is 29.75, and the commission is 0.39 you will get (100 - 0.39) * 29.75 = 2963.3975RUR. You surely know that there are N different currencies you can deal with in our city. Let us assign unique integer number from 1 to N to each currency. Then each exchange point can be described with 6 numbers: integer A and B - numbers of currencies it exchanges, and real RAB, CAB, RBA and CBA - exchange rates and commissions when exchanging A to B and B to A respectively. Nick has some money in currency S and wonders if he can somehow, after some exchange operations, increase his capital. Of course, he wants to have his money in currency S in the end. Help him to answer this difficult question. Nick must always have non-negative sum of money while making his operations. Input The first line contains four numbers: N - the number of currencies, M - the number of exchange points, S - the number of currency Nick has and V - the quantity of currency units he has. The following M lines contain 6 numbers each - the description of the corresponding exchange point - in specified above order. Numbers are separated by one or more spaces. 1 ≤ S ≤ N ≤ 100, 1 ≤ M ≤ 100, V is real number, 0 ≤ V ≤ 103. For each point exchange rates and commissions are real, given with at most two digits after the decimal point, 10-2 ≤ rate ≤ 102, 0 ≤ commission ≤ 102. Let us call some sequence of the exchange operations simple if no exchange point is used more than once in this sequence. You may assume that ratio of the numeric values of the sums at the end and at the beginning of any simple sequence of the exchange operations will be less than 104. Output If Nick can increase his wealth, output YES, in other case output NO.

用c++解决Several currency exchange points are working in our city. Let us suppose that each point specializes in two particular currencies and performs exchange operations only with these currencies. There can be several points specializing in the same pair of currencies. Each point has its own exchange rates, exchange rate of A to B is the quantity of B you get for 1A. Also each exchange point has some commission, the sum you have to pay for your exchange operation. Commission is always collected in source currency. For example, if you want to exchange 100 US Dollars into Russian Rubles at the exchange point, where the exchange rate is 29.75, and the commission is 0.39 you will get (100 - 0.39) * 29.75 = 2963.3975RUR.

1、兑换货币 exchg.cpp 问题描述: 在我们城市里有几个正在工作的兑换站,我们假设每个兑换站专门兑换两钟货币。可以有多间兑换站都兑换同样的两种货币,不过每间兑换站都有它们自己的汇率。A对B的汇率就是,多少B能换1A。另外每个兑换站都会从你兑换的金钱中收取一定的佣金,佣金就是从兑换中赚取。 例子:如果你想100 US 换成 RUSSIAN RUBLES在兑换站,那里的汇率是29。75,而手续费是,0.39,那么你就能得到,(100-0.39)*29.75= 2963.3975RUR 你的确知道了你有货币N要在你的城市兑换。让我们为每一种货币输入唯一的一个正整数(1~N)表示。然后,每个兑换站输入6个数:货币A,B的存放量,A换B,B换A 的汇率和A换B,B换A的手续费。 NICK 有一些钱想兑换成S,不知为何,在一些交易后,他的财产增加了。当然他还是想把钱兑换成S,帮他解决这难题。并且,在交易中NICK不能亏损。 输入格式: 第一行输入N(持有的货币),M(兑换站的数量),S(NICK要兑换的货币),V(NICK有的货币数量),以下的M行输入6个数:各个种属性。 1〈=S〈=N〈=100,1〈=M〈=100,V是实数,0〈=V〈=103。 每个兑换站的汇率和手续费都是实数,保留最多两位小数,10-2〈=汇率〈=102,0〈=手续费〈=102。 为了让兑换程序更加简单,如果兑换的次数多于一次,那么就要保证兑换后的数值必须大于兑换前,并且兑换次数必须小于104。 输出格式: 如果能增加他的财富,那么输出YES,不能就输出NO。 exchg.in 3 2 1 20.0 1 2 1.00 1.00 1.00 1.00 2 3 1.10 1.00 1.10 1.00 exchg.out YES 请分析代码的错误,并修正
