3Sum Closest Given an array S of n integers, find three integers in S such that the sum is closest to a given number, target. Return the sum of the three integers. You may assume that each input would have exactly one solution. For example, given arr…
3Sum Given an array S of n integers, are there elements a, b, c in S such that a + b + c = 0? Find all unique triplets in the array which gives the sum of zero. Note: Elements in a triplet (a,b,c) must be in non-descending order. (ie, a ≤ b ≤ c) The…

1).2sum 1.题意:找出数组中和为target的所有数对 2.思路:排序数组,然后用两个指针i.j,一前一后,计算两个指针所指内容的和与target的关系,如果小于target,i右移,如果大于,j左移,否则为其中一个解 3.时间复杂度:O(nlgn)+O(n) 4.空间:O(1) 5.代码: void twoSum(vector<int>& nums,int numsSize,int target,vector<vector<int>>& two…

n数求和,固定n-2个数,最后两个数在连续区间内一左一右根据当前求和与目标值比较移动,如果sum<target,移动较小数,否则,移动较大数 重复数处理: 使i为左至右第一个不重复数:while(i != 0 && i<n-2 && a[i] == a[i-1]) i++; 使r为右至左第一个不重复数(原序最后一个):while(r>i && r+1<n && a[r] == a[r+1]) r--; 15. 3Sum…
