Can you solve this real interview question? Intersection of Two Arrays - Given two integer arrays nums1 and nums2, return an array of their intersection. Each element in the result must be unique and you may return the result in any order. Example 1:
arr2 = [1,2,5,7,9] arr3 = [1,3,4,5,8] 9 1 2 3 4 5 6 › [1,2,3,4,5] [1,2,5,7,9] [1,3,4,5,8] [197,418,523,876,1356] [501,880,1593,1710,1870] [521,682,1337,1395,1764] Source 该题目是 Plus 会员专享题 ...
Each element in the result should appear as many times as it shows in both arrays. The result can be in any order. Follow up: What if the given array is already sorted? How would you optimize your algorithm? What if nums1's size is small compared to num2's size? Which algorithm is...
Leetcode:Question4--Median of Two Sorted Arrays 题目描述 解法 这道题目假如采取最普通的做法,即为将两个数组结合在一起,再进行排序,然后取出直接取出中位数即可。排序的算法最优复杂度为 O(nlogn),而取出中位数的复杂度为O(n),遍历两个数组的复杂度也是O(n),所以整个算法的复杂度为O(nlogn),明显超过...
