其它解法六:LeetCode 中国的普通解法,和解法二类似 class Solution: def twoSum(self, nums: List[int], target: int) -> List[int]: n = len(nums) for i in range(n): for j in range(i + 1, n): if nums[i] + nums[j] == target: return [i
result[0] =i result[1] =jreturnresult[:]//返回结果} } }returnnil } 回到顶部 四、C代码 int* twoSum(int* nums,intnumsSize,inttarget) {int*a = (int*)malloc(2*sizeof(int));for(inti =0;i < numsSize;i++){for(intj = i +1;j < numsSize;j++){if(nums[j] == target -nums...

Leetcode Solutions(一) two-sum Two Sum 题目 给定一个整数数组和一个目标值,找出数组中和为目标值的两个数。 你可以假设每个输入只对应一种答案,且同样的元素不能被重复利用。 示例: 给定 nums = [2, 7, 11,…
LeetCode_1. Two Sum_Solution,原题链接原题中文链接一、题目描述二、题目分析1,常规解法这道题目的意思是给定一个数组和一个值,要求出这个数组中两个值的和等于这个给定值target。输出是有要求的:坐标较小的放在前面,较大的放在后面。这俩坐标不能为零。因此我们可以
class Solution: def twoSum(self, nums: List[int], target: int) -> List[int]: hashtable = dict() for i, num in enumerate(nums): if target - num in hashtable: return [hashtable[target - num], i] hashtable[nums[i]] = i ...
这个问题很经典,对于3Sum,先确定一个数字,然后这个问题就退化成了2Sum的问题。针对2Sum,先对数组排序,然后使用双指针匹配可行解就可以解决,虽然可以考虑使用HashMap加速搜索,但是对于本题使用HashMap的与否的时间复杂度都一样,都是O(nlog(n))。可以参考这个链接: 求和问题总结(leetcode 2Sum, 3Sum, 4Sum, K Su...
Can you solve this real interview question? Two Sum - Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may n
class Solution { public int[] twoSum(int[] numbers, int target) { int[] res = new int[2]; int i = 0, j = numbers.length - 1,temp;//i为左指针,j为右指针 while (i < j) { temp=numbers[i] + numbers[j];//先记录两数之和 ...
