) Unordered array Delete (query + fill hole) O (N) Ordered array deletion (query + fill hole) O (N) Why not use data to solve everythingAn unordered array is inserted (O (1) time), and the query spends (O (N) time). An ordered array query spends (O (logn) time), but inserts a missing cost (O (N) time). And the deletion takes (O (N) time). So a data structur

1 and 0 occurrences of the place, 1 and 0 appear two times, since there is no 0, then 1 is occupy the first and second position (please read this sentence carefully, this sentence read, the whole algorithm understand). Then we put one of the 1 in the position of the second position of the 1 b[1], while c[1]-1, because we have already lined up a 1.Next, I=1,a[1]=2,c[2] is less than or equal to 2 of the number of occurrences, c[2]=4, then to rank it in fourth place, that is b[3] position, while c

If there are 10 data items, there are 20 copies. The number of copies is p

(Another scenario I came up with was to show a file tree like Windows Explorer on the front end)I thought for a long time, did not think of a circular solution, and later found the answer on the StackOverflow:var plain2Tree = function (obj) { var key, res for(key in obj) { var parent = obj[key].parent if(parent === ‘‘) { res = obj[key] } else { obj[parent][key] = obj[key] } } return res}This code is the use of JavaScript inside the reference type, then th

We have introduced the linear structure. The data elements in the linear structure are one-to-one relationships. This chapter and the next chapter introduce two important non-linear structures: Tree Structure and graph structure. The tree structure is a one-to-many nonlinear structure, which is very similar to the trees in nature. Data elements have both branch a

structure of linear tables, where the time complexity is O (1), regardless of the location of the data being stored or read. When inserting or deleting, the time complexity is O (n), indicating that it is more suitable for the number of elements stable, not often inserting and deleting elements.Advantages:① no need to add additional storage space to represent the logical relationship between elements in a table② can quickly access elements from anywh

to implement, tracking the algorithm is not straightforward.Other interval sequencesThe selection interval sequence can be called a magic. Only the formula h=h*3+1 generation interval sequence is discussed here, but the application of other interval sequences has achieved varying degrees of success. There is only one absolute condition, that is, the gradually decreasing interval must be equal to one at a time, so the last order is a normal insertion sort.The efficiency of the hill sortSo far, n

Recently at home in the evening to see algorithems,4th Edition, I bought the English version, think this book is relatively easy to understand, and "figure Code and Mao", take advantage of this opportunity to learn to do notes, this will also be impressive, this is the reason for writing this series of articles. In addition, Princeton University also has this book in the Coursera of the Open class, there is

data structures and algorithms (Python)Bubble SortBubble Sort (English: Bubble sort) is a simple sorting algorithm. It iterates over the sequence of columns to be sorted, compares two elements at a time, and swaps them if their order is wrong. The work of iterating through the series is repeated until no more swapping is needed, meaning that the sequence is sorte

I. Large O notationLarge o notation is not an algorithm. It is used to indicate how quickly an algorithm solves a problem. In general, we describe how quickly a thing is done in terms of time, for example, how many minutes I have completed a computational problem. But the algorithm is difficult to use accurate time to describe, so we use the algorithm to solve the problem of a total number of steps to represent the speed of the algorithm.Using the first two search methods for example, simple fin
