java编程之Noncompliant; %n should be used in place of n to produce the platform-specific line separato

在java编程时，难免会用到\n来实现换行，但是我相信大家应该知道windows上的换行与linux的换行符是不一样的，当我们使用java.util.Formatter, java.lang.String...java.io.PrintStream，java.io.PrintWriter类的format方法以及java.io.PrintStream或者java.io.PrintWriter类的printf(...)方法时，应该使用%n代替...\n，这样java程序在实际执行时运行到该句时就会根据平台产生相应的换行效果。

LeetCode 19：删除链表的倒数第N个节点 Remove Nth Node From End of List

给定一个链表，删除链表的倒数第 n 个节点，并且返回链表的头结点。...Given a linked list, remove the n-th node from the end of list and return its head....示例：给定一个链表: 1->2->3->4->5, 和 n = 2. 当删除了倒数第二个节点后，链表变为 1->2->3->5. 说明：给定的 n 保证是有效的。...最先想到的方法就是遍历整个链表得到长度，减去 n 得到实际应该删除的节点的位置了。然而由于单链表删除操作的特殊性，得到位置之后仍然需要再遍历一次来删除该节点。...假设链表长度为 L ，定义一个指针先走 n 步，此时该指针还剩下 L-n 个节点即可完成该链表的遍历。而第 L-n 个节点不就是题目要求的的要删除的倒数第 n 个节点吗？

用一次就爱上的 Array.from —— 构建 m*n 数组的绝对优雅姿势

--------------------------------------------------------------------- 用一次就爱上的 Array.from —— 构建 m*n...表面上看没毛病，打印出来也是一个 m×n 的全零数组。...(0) 这个长度为n，值全为0的数组的引用作为.fill()的值，所以最终生成的数组每个元素都是相同的长度为n，初始值为0的数组。...2、用 Array.from 配合函数工厂生成多维数组使用 Array.from，我们可以为每一项动态生成一个新数组实例： const matrix = Array.from({ length...再回头看那一行： const matrix = Array.from({ length: m }, () => Array(n).fill(0)); 是不是比嵌套循环看起来更舒服？
