One of the basic Set operations is to get the intersection of two sets. In mathematical terms, this is expressed as A ∩ B (i.e. elements that are common in both "A" and "B"). To get the intersection of two
Given two arrays a[] and b[], each containing n distinct 2D points in the plane, design a subquadratic algorithm to count the number of points that are contained both in array a[] and array b[]. 题目的目标就是计算重复point的个数,很简单,代码如下 1importjava.awt.Point;2importjava.util...
This function finds the intersection of two sets, i.e., elements that are common to both sets. JavaScript: let intersection = (set1, set2) => new Set([...set1].filter(val => set2.has(val))); // Example console.log(intersection(new Set([1, 2, 3]), new Set([2, 3, 4])...
