https://oj.leetcode.com/problems/remove-duplicates-from-sorted-array/ 用一个cnt记录不重复的部分,后面每遇到不重复的cnt++即可。 classSolution {public:intremoveDuplicates(intA[],intn) {if(n==0)return0;intlast=A[0]-1;intcount=1;for(inti=0;i<n;i++){if(A[count-1]!=A[i]) { A[cou...
Follow up for ”Remove Duplicates”: What if duplicates are allowed at most twice? For example, Given sorted array A = [1,1,1,2,2,3], Your function should return length = 5, and A is now [1,1,2,2,3] 之前的想法是再加一个计数的变量就行了 intremoveDeplicates1(intA[],intn) {...
The computational complexity of that is O(1) (it’s constant time), that means no matter how largeexistingUsersgets, it will always take the same amount of time to look up whether or not an id is in the Set. You could do the same with an Array (list), with a higher performance c...
题目链接:https://leetcode.com/problems/remove-duplicates-from-sorted-array/ 题目: once Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array nums =[1,1,2],2, with the first two elements of nums being1and2 思路: ...
Explanation: 2 appears twice in the linked list, so all 2's should be deleted. After deleting all 2's, we are left with [1,3]. 1. 2. 3. Example 2: Input: head = [2,1,1,2] Output: [] Explanation: 2 and 1 both appear twice. All the elements should be deleted. ...
【题目】Given an integer array nums, find the sum of the elements between indices i and j (i ≤ j), inclusive. The update(i, val) function modifies nums by updating the element at index i to val. Example: 代码语言:javascript 代码运行次数:0 运行 复制 Gi...
【题目】Given a non-empty array containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal. Note: Each of the array element will not exceed 100. The array size will not exceed 200. Example 1: ...
