As one of the ten classic sorting algorithms, quick sort often appears in the interview field. It requires either handwritten quick sort or a variant of quick sort. In order to facilitate review, quick sort is hereby summarized 1. Fledgling Given an array arr and a number num, please put the number less than or equal to num on the left ...

Load balancing -- consistent Hash algorithm Before talking about consistency hash, you need to hash the hash. For hash, you only need the time complexity of O(1), and then you can calculate the result. For example, in our HashMap, the hash algorithm is used to calculate the subscript of the key, but it is similar to hashing the hash value afte ...

Fitting, as the name suggests, is to find the mathematical relationship between data through the analysis of data. The deeper the understanding of the essence of this relationship, the higher the degree of fitting, and the clearer the relationship between data. Fitting includes linear fitting and nonlinear fitting (polynomial fitting). This pap ...

1. DFS basic framework DFS in Figure The core issue is "Traversing a two-dimensional array" The two-dimensional array traversal framework is as follows: void dfs (int[][] grid , int i , int j , boolean[] visited) { int m = gird.length , n = grid[0].length; //Check for out of bounds if (i < 0 || j < 0 || i >= m || j & ...

Algorithm overview Algorithm classification Ten common sorting algorithms can be divided into two categories: Comparison sort: the relative order between elements is determined by comparison. Because its time complexity cannot exceed O(nlogn), it is also called nonlinear time comparison sort.Non comparison sort: it does not determine the rel ...
