Given an integer array of sizen, find all elements that appear more than⌊ n/3 ⌋times. The algorithm should run in linear time and in O(1) space. 之前也有类似得题,找出出现次数大于一般的元素,两道题一个想法。 publicclassSolution {publicList<Integer> majorityElement(int[] nums) { ...
As the test above shows, we initialize aMutableListwith two elements. Then, we use the same approach to add two elements to the list using theadd()method and the += operator. The test passes if we give it a run. 6. Adding an Element to a Read-OnlyList ...

因此归并排序或者多路归并就成为了排序的选择。 归并排序分为拆分、合并两个阶段： 1. 拆分 需要找出链表中间节点，并根据中间节点拆分成两个独立的链表，递归直到拆分成单个节点为止。 2. 合并 由于此时每个链表都为单节点，所以对于拆分的两个子链表实质上是有序链表合并问题。
(If the list contains no elements, the new element becomes the sole element on the list.) The new element is inserted before the implicit cursor: a subsequent call to next would be unaffected, and a subsequent call to previous would return the new element. (This call increases by one the...
