Leetcode.350 Intersection of Two Arrays IIGiven two arrays, write a function to compute their intersection.Example 1:Input: nums1 = [1,2,2,1], nums2 = [2,2] Output: [2,2] Example 2:Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4] Output: [4,9] ...
Follow up 2 nums1 length is smaller. 用双指针先sort两个array明显没有利用到num1.length小的特性. 若是用HashMap来记录num1每个element出现频率再iterate nums2, 那么Time Complexity: O(m + n), m = nums1.length, n = num2.length. Space: O(m). 或者sort nums1 再对每一个num2的element在 s...
Given two arrays, write a function to compute their intersection. Example: Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. Note: 1、Each element in the result must be unique. 2、The result can be in any order. 要完成的函数: vector<int> intersection(vector<int>& ...
LeetCode.349--intersection-of-two-arrays 一、题目链接 两个数组的交集 二、题目描述 给定两个数组nums1和nums2,返回它们的交集。输出结果中的每个元素一定是 唯一 的。我们可以 不考虑输出结果的顺序 。 示例1: 输入:nums1 = [1,2,2,1], nums2 = [2,2...
What if the given array is already sorted? How would you optimize your algorithm? What if nums1’s size is small compared to nums2’s size? Which algorithm is better? What if elements of nums2 are stored on disk, and the memory is limited such that you cannot load all elements into ...
757. Set Intersection Size At Least Two 参考链接: Python Set intersection() An integer interval [a, b] (for integers a < b) is a set of all consecutive integers from a to b, including a and b. Find the minimum size of a set S such that for every integer interval A in intervals...

System.out.println( "Subtract: " + ArrayUtils.toString( subtract.toArray( ) ) ); The previous example performs these four operations on two List objects, a and b, printing the results with ArrayUtils.toString( ): Java代码 A: {1,2,2,2,3,3,4,5} ...
3.该代码最后返回的时候使用了数组的拷贝的方式。Arrays.copyOf(array, count)。 解法二:排序+双指针 解题思路: 1)对数组nums1进行排序; 2)对数组nums2进行排序; 3)遍历数组nums1和nums2中元素,并比较对应的元素, 若相等,则将其保存到输出结果中,并变化两个数组对应的索引 ...
