Fast sorting, as its name is, is the fastest sort on average, in the case of 2LN2 (Nlogn), about 1.39nlogn, in the same complexity as O (NLOGN) sorting algorithm, is the least constant coefficient algorithm, the worst case can be as high as O (n^2), However, the probability of worst-case occurrence can be greatly reduced by using the improved stochastic fast-scheduling algorithm. Not only that, the fast sort is also an algorithm that can run in-place, and its operation requires only O (1). In pr

Sorting method is more famous, the specific algorithm to see:This blog is easy to say: http://blog.csdn.net/morewindows/article/details/6684558This is the basis for fast sorting, implemented in code as follows:voidDiviedsort (int* Arr_p,intStartintend) { intLeft,right,i=0; intPivot,result; BOOLFlag; Flag=TRUE; Pivot=Arr_p[start]; Right=end; Left=start; #ifDEBUGprintf ("pivot:%d\r\n",

Quick sort, also called divide-and-trade sorting. A fast sorting algorithm based on divide-and-conquer method is implemented.This paper mainly discusses the use of JavaScript to realize the rapid sequencing of In-place thoughtDivide and conquer law:in computer science, divide-and- conquer method is a very important algorithm paradigm based on branching recursion. The literal interpretation is "divide and conquer", that is, to divide a complex problem into two or more identical or similar sub-pro

Fast sorting is also a sort of sorting algorithm. Quick sort and Merge sort is complementary: merge sort sorts the array into two sub-arrays, merges the ordered Subarray to sort the entire array, requires an extra array, and the quick sort is ordered when two sub-arrays are ordered, the entire array is natural and orderly, and the fast sort does not produce extra arrays.For decimal groups (nA quick sort can be made up of the following steps:1. Returns if the number of elements in the array s is

Quick Sorthttp://m.blog.csdn.net/blog/u013071074/36867589 Quick Sort is a sort of algorithm developed by C. A. R. Hoare. The basic idea is the basic idea is that by a trip to the sorting of the records separated into two separate parts, some of the records of the keywords are smaller than the other part of the keyword, you can continue to order the two parts of the record to achieve the order of the whole sequence. Quick sort use the divide-and-conquer method to divide a string (lis

average time, mainly because of hardware, each trip needs to specify a "pivot" (that is, as the value of the demarcation point). All comparisons involved in a trip are compared with this "pivot, then we can put this "pivot" in the register, so that the efficiency will naturally be greatly improved. In addition, the efficiency of fast sorting is inseparable from

recursive decomposition and merging of the layers, the algorithm of the merging sort has the time complexity ofO (N*LOGN)Merge sort is a stable sortQuick sorting (Quick sort)The simplest interchange sort is a bubbling sort, and a quick sort is an improvement to the bubbling sort.First select a keyword from the sequence to be sorted, called the pivot, by the comparison of the keyword and the pivot to divide

Select the elements to do the pivot elementThe usual, not well-thought-out option is to use the first or last element as a pivot element. Select the first element as the pivot element of the program example can refer to the topic of the previous article "Learning in the fast sequence", and select the last element to use as a hub element of the program example can

processing, it can achieve a programmable clock frequency, each hardware module can have its own frequency, and each hardware module can switch the clock independently. So it needs to be managed! Our board mainly involves the following clock types: PLL: clock from the clock source, which can be understood as the xtal clock source; Pll_cpu: When providing clock for other hardware modules; Pll_usb: USB Host Controller clock Fclk: CPU clock (arm926) Hclk: hardware module clock on AHB
