There are four equality algorithms in ES2015: Abstract (non strict) equality comparison (= =)Strict equality comparison (= = =): for array prototype. indexOf, Array. prototype. LastIndexOf, and case matchingSame value zero: used for% TypedArray% and ArrayBuffer constructors, as well as Map and Set operations, and will be used for string in ES2 ...

Will share some classic exercises and solutions being done, and write your own understanding if you are interested. If you are interested, you can refer to it. There are duplicate elements Given an integer array, determine whether there are duplicate elements. If a value exists and appears in the array at least twice, the function returns ...

"Li Kou" question 1673: find the most competitive subsequence (stack) Give you an integer array num and a positive integer k, and return the most competitive num subsequence with length K. A subsequence of an array is a sequence obtained by deleting some elements from the array (elements may not be deleted). In the first different ...

Sort, also known as Sort Algorithm, is the process of sorting a set of data according to a specified message. Sorted classification: 1) Internal sorting: means that all data that needs to be processed is loaded into internal memory for sorting. Internal sorting includes insert sort (direct insert or Hill sort), select sort (simple sort and heap ...

preface This week, I share a double pointer related algorithm problem. The author's level is limited. If you have any questions, please leave a message at the bottom of the article! Key words: double pointer. subject Sum of three Give you an array num containing n integers. Judge whether there are three elements a, b and c in num, so tha ...

1, Experimental purpose Through the simulation of page, page table, address conversion and page replacement process, we can deepen the understanding of the page replacement principle and implementation process of virtual page memory management system. 2, Overall design (including background knowledge or basic principles and algorithms, or modul ...

1, Minimum path coverage definition Minimum path covering means that in a directed acyclic graph, all points in the graph are covered with the least and disjoint simple paths. solution ① Disassemble each point in the original drawing (disassemble point u into U and u+n); ② Set each edge < u, V > in the original graph to the correspond ...
