题目大意:给长度N的A1.....An 求(Ai-Aj)MAX 枚举n^2 其实动态维护最大值就好了 #include<iostream> #include<cstdio> using namespace std; ],n,ans,MAX; int main() { scanf("%d",&t); while (t--) { scanf("%d",&n); ;i<=n;i++) scanf("%d",…

这道题使用暴力解法O(n*n)会超时,那么用动态维护最大值可以优化到O(n).这种思想非常实用. #include<iostream> #include<cstdio> #include<cstdlib> #include<cstring> #include<string> #include<cmath> #include<map> #include<set> #include<vector> #i…

题意:给出n个数,找出两个整数a[i],a[j](i < j),使得a[i] - a[j]尽量大 从小到大枚举j,在这个过程中维护a[i]的最大值 maxai晚于ans更新, 可以看这个例子 1 8 9 10 11 正确的应该是-1 如果更早更新的话,算出来就是0 用数组来存的 #include<iostream> #include<cstdio> #include<cstring> #include <cmath> #include<stack…

.Net中我们通常使用Random类生成随机数,在一些场景下,我却发现Random生成的随机数并不可靠,在下面的例子中我们通过循环随机生成10个随机数: ; i < ; i++) { Random random1 = new Random(); Console.WriteLine(random1.Next()); } 测试生成随时基本都是相同的结果: 很显然上面的结果是不靠谱的,为什么会这样呢,因为微软的Random类,发现在C#中生成随机数使用的算法是线性同余法,这种算法生成的不是绝对随机,而…

正则表达式的本质是使用一系列特殊字符模式,来表示某一类字符串.正则表达式无疑是处理文本最有力的工具,而.NET的System.dll类库提供的System.Text.RegularExpressions.Regex类实现了验证正则表达式的方法.Regex 类表示不可变(只读)的正则表达式.它还包含各种静态方法,允许在不显式创建其他类的实例的情况下使用其他正则表达式类. 正则表达式的字符代表的说明: Normal 0 7.8 磅 0 2 false false false EN-US ZH-CN…
