Storage structure of sequence table (1) When a high-level programming language such as c language is used to describe the problem of data structure, the method to realize the sequential storage structure is to use array. (2) There are two kinds of arrays: static array and dynamic array. The application and release of static array storage space ...

In situ hash algorithm The in-situ hash algorithm is used to solve the problem with spatial complexity of O(1), and the result range is between [0, len (Num)], and num is the solution array provided by the problem. The in-situ hash algorithm is mainly used in the array solution with the result range of [0, len (Num)]. The space complexity is ...

Leetcode one question per day (two questions) - 3.4 + 3.3 preface I wrote the daily question of these two days, learned some new knowledge points, and made a comb and summary. 3.3 add up Given a non negative integer num, the numbers on each bit are added repeatedly until the result is a single digit. Return this result. Title Link ...

1. Title Description Give you an integer array nums. In nums, the range of subarray is the difference between the largest element and the smallest element in the subarray. Returns the sum of all subarray ranges in num. A subarray is a sequence of consecutive non empty elements in an array. Example 1: Input: num = [1,2,3] Output: 4 Explanatio ...

Containers in STL: set container common interfaces and usage of multiset container: set / multiset container: also known as a set, all elements are automatically sorted when inserted (from small to large, i.e. ascending) Bottom structure of set / multiset container: these two containers belong to associative containers, and the bottom stru ...

1. Hash table Note 1 Note 2 Hash table (also known as hash table) is a data structure that is accessed directly according to the key value. That is, it accesses records by mapping key values to a location in the table to speed up the search. This mapping function is called hash function, and the array storing records is called hash table. Hash ...
