题目 There are two sorted arrays nums1 and nums2 of size m and n respectively. Find the midian of the two sorted arrays. The overall run time complexity should be O(log(m+n)). You may assume nums1 and nums2 cannot be both empty. Example1: nums1 = [1,
25.数组 1)声明数组: ①构造函数创建数组 var arr = new Array(); console.log(arr): //[] var arr = new Array(20); //设置数组的长度为20 console.log(arr); //[,,,,,,,,,,,] 单个打印的值为undefined var arr = new Array('zhangsan', 'lisi'); console.log(arr); //['z
一.数组的声明方法一:[构造函数形式声明] var array = new Array(); //[] var array = new Array(10); //数组长度:array.length = 10; var array = new Array('tom',20,null); //['tom',20,null] 方法二:[数组字面量形式创建] var array = []; //[] var array = [1,2,3,'tom']; //[1,2,3,'tom'] 访问数组下标越界的
Maximum Subarray Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [−2,1,−3,4,−1,2,1,−5,4], the contiguous subarray [4,−1,2,1] has the largest sum = 6. click to show
最近在做PBOC圈存时用到了3DES的加密解密以及MAC计算问题,在网上了解一些知识,复制了一些demo学习,我这里没有深入研究,只是把我用到的和了解的做个总结,便于以后使用和学习. 3DES分双倍长和三倍长,我使用到的是双倍长,加密模式为ECB,代码如下 public static class EncryptUtils { //构造一个对称算法 private static SymmetricAlgorithm mCSP = new TripleDESCryptoServiceProvider
