#349. Intersection of Two Arrays
Given two arrays, write a function to compute their intersection.
Example:
Given nums1 = [1, 2, 2, 1]
, nums2 = [2, 2]
, return [2]
.
Note:
题解:我想到的是用set,有点懒,其实是不知道咋做好,直接上代码。
class Solution { public: vector<int> intersection(vector<int>& nums1, vector<int>& nums2) { vector<int> v(0); vector<int> ret; if(nums1.size()==0||nums2.size()==0) return v; set<int> save; set<int> result; for(int i=0;i<nums1.size();i++) { save.insert(nums1[i]); } for(int i=0;i<nums2.size();i++) { if(save.find(nums2[i])!=save.end()) { result.insert(nums2[i]); } } set<int>::iterator it; for(it=result.begin();it!=result.end();it++) { ret.push_back(*it); } return ret; } };
