Intersection of Two Arrays(两个数组的交集) 1、题目描述 2、分析 给定两个数组,编写一个函数来计算它们的交集。可以从例子上看出,这道题只需要找到两个数组中相同的数字就好,所以现将第一个数组放入一个set,set里没有重复的元素,并且是排好序的。之后遍历第二个数组看第二个数组中的元素是不是在set中,...
What if the given array is already sorted? How would you optimize your algorithm? What ifnums1's size is small compared tonums2's size? Which algorithm is better? What if elements ofnums2are stored on disk, and the memory is limited such that you cannot load all elements into the memo...
350. Intersection of Two Arrays II iven two arrays, write a function to compute their intersection. Example:Given nums1 =[1, 2, 2, 1], nums2 = [2, 2], return [2, 2]. Note: Each element in the result should appear as many times as it sh......
Which algorithm is better? What if elements ofnums2are stored on disk, and the memory is limited such that you cannot load all elements into the memory at once? 这道题是之前那道Intersection of Two Arrays的拓展,不同之处在于这道题允许返回重复的数字,而且是尽可能多的返回,之前那道题是说有重...
If the two elements are the same, forward both pointers and put the element to the return array If the two elements are not the same, move the smaller one's pointer forward Keep doing the above two steps until it hit the end of any one of the arrays. class Solution: def intersect(se...
