[LeetCode] 122.Best Time to Buy and Sell Stock II 买股票的最佳时间之二

Say you have an array for which the ith element is the price of a given stock on day i.

Design an algorithm to find the maximum profit. You may complete as many transactions as you like (ie, buy one and sell one share of the stock multiple times). However, you may not engage in multiple transactions at the same time (ie, you must sell the stock before you buy again).

这道跟之前那道Best Time to Buy and Sell Stock 买卖股票的最佳时间很类似，但都比较容易解答。这道题由于可以无限次买入和卖出。我们都知道炒股想挣钱当然是低价买入高价抛出，那么这里我们只需要从第二天开始，如果当前价格比之前价格高，则把差值加入利润中，因为我们可以昨天买入，今日卖出，若明日价更高的话，还可以今日买入，明日再抛出。以此类推，遍历完整个数组后即可求得最大利润。代码如下：

C++ 解法：

class Solution {
public:
    int maxProfit(vector<int>& prices) {
        int res = 0, n = prices.size();
        for (int i = 0; i < n - 1; ++i) {
            if (prices[i] < prices[i + 1]) {
                res += prices[i + 1] - prices[i];
            }
        }
        return res;
    }
};

Java 解法：

public class Solution {
    public int maxProfit(int[] prices) {
        int res = 0;
        for (int i = 0; i < prices.length - 1; ++i) {
            if (prices[i] < prices[i + 1]) {
                res += prices[i + 1] - prices[i];
            }
        }
        return res;
    }
}

C++中Boost.Chrono时间库的使用方法

前言大家应该都有所体会,时钟这个东西在程序中扮演者重要的角色,在系统编程的时候睡眠.带超时的等待.带超时的条件变量.带超时的锁都会用到,但是往往对特定系统依赖性很大,感觉即使不考虑系统的跨平台性,如果能使用一个稳定的接口,同时如果能够方便的对时刻.时段等进行相关的操作和运算,将是再好不过的了. 在boost库中和时间相关的库有Boost.DateTime和Boost.Chrono,前者专注于时间时刻以及本地化相关的内容,而后者主要是时刻.时长和时间的计算等内容.当然,C++11标准已经支持st
