5. Quick Sort

First, the basic ideaBy dividing the sorted data into separate parts, one part of the data is smaller than the other, and then the two parts of the data are sorted quickly, and the whole sorting process can be recursive to make the whole sequence orderly. In the process of segmentation, the choice of pivot element is very important. The reasons are as follows: (1) Two parts of the data is the hub element as the demarcation point , less th

directly above (the screen).· The y-axis deviates from you in the right direction. Parent Coordinate: the coordinate system that uses the parent object of the selected object. If the object is not linked to a particular object, then it is the child of the world, that is, the parent coordinate is the same as the world coordinates. Local coordinates: Use the coordinate system of the selected object. The local coordinates of an object come from its pivot

Quick sort of Python

Quick sorting (Quick sort)The basic idea of quick sorting: to separate the pending records into two separate parts by a sort of sequencing, where some of the recorded keywords are smaller than the others, then the two parts of the records can be recursively sorted to achieve the order of the whole sequence.1. Algorithm Description: Another divide and conquer Divides the array into two parts, and then sorts the parts independently First select a

Fast Sorting algorithm idea: Select a pivot element, treats the sort sequence to divide, after the division the sequence one part is smaller than the pivot element, one part is bigger than the pivot element, then carries on these two good dividing sequences to carry on the above process.

Knowledge in quick sorting: Key element selection and algorithm efficiency

Generally, the first or last element is used as the pivot element without full consideration. If the input is random, this is acceptable. However, if the input is pre-ordered or backward, such a pivot element produces a poor segmentation, because all elements are either input S1 or input S2. What's more, this happens in all recursive calls. Select the beginning and end elements as the hub element Generally,

Data Structure Basics (4)--Quick sort

Fast sorting is the most popular and the fastest sorting algorithm (c + + STL's sort function is the implementation of the fast sort); Quick Sort (Quicksort) is an improvement to the bubbling sort.by C. A. R. Hoare was introduced in 1962. Its basic idea is: by a trip to sort the data will be sorted into two separate parts, one part of all the data is smaller than the other part of all the data, and then this method to the two parts of the data to be quickly sorted, the entire sorting process can

Reference book: Data structure and algorithm analysis--c language descriptionFast sequencing is the fastest known sorting algorithm in practice, with its average time complexity O (NLOGN). Of course, in the worst case, O (n^2), but a little effort can avoid this situation.Like merge sort, fast sorting is also a recursive algorithm for splitting, which can be simply represented as follows:The basic algorithm for sorting the array s is made up of the following simple four steps.1, the array elemen
