1. What is the data structure: There have been many different interpretations of the concept of data structure, and there are also many different controversies. This only represents my personal understanding. Data Structure: how can we store a large number of complex problems in reality in a specific data type and storage structure to the primary memory (memory), and on this basis to implement Functions (such as searching for an element and deleting an element). The corresponding operation is al

Document directory Space complexity The fastest sorting algorithm is bucket sorting. Time Complexity N ^ 2 indicates the square of N. Selecting sorting is sometimes called directly selecting sorting or simply selecting sorting. Sorting Method Average time Best time Worst time Sort buckets (unstable) O (N) O (N) O (N)

the memory space occupied when the algorithm program is running. Time Complexity First, let's talk about the problem of time efficiency. The time efficiency here refers to the execution time of the algorithm. The speed of time is a relative concept, so it comes to the algorithm, what measures should we use to measure the time efficiency (execution time) of an algorithm? At the beginning, we came up with

memory is needed to run the program. In addition to requiring storage space and storing the instructions, constants, variables, and input data used by the store itself, a program needs some working units to manipulate the data and a secondary space to store some of the information needed for realistic computing.　　The storage space required for program execution

Candy [leetcode] O (n) time complexity, O (1) space complexity method, candyleetcode The relationship between ratings [I + 1] and ratings [I] is as follows: 1. Equal. When the value is equal, ratings [I + 1] corresponds to 1 candy. 2. ratings [I + 1]> ratings [I]. In this case, you need to find the incremental Sequence starting with ratings [I. 3. ratings [I + 1]

Algorithm Analysis The same problem can be solved by different algorithms, and the quality of an algorithm will affect the efficiency of the algorithm and even the program. Algorithm analysis aims to select appropriate algorithms and improve algorithms. The evaluation of an algorithm mainly involves time complexity and space complexity. 1. Time

put on N3 above N4 N4 N3 N3 N2 N2 N2 N2 N2 N2 N1 N1 N1 N1 N1 N1 N1 I finally bought the last one! I found that only 0.5 is needed to stack this book on N3, and 0.55 is needed to stack it on N4! Of course, I will not choose the one that costs too much. N4 N4 N5 N3 N3 N2 N2 N2 N2 N2 N2 N1 N1 N1 N1 N1 N1 N1 So I bought the book. I bought three, four, three, two, and one. The purchase method is the same as that in the teaching material. Iv. algorithm time c
