) operation, and then take the number on the line, in order to simplify the understanding, you can take the number of the top of the heap into an empty But here in order not to open the extra memory to put out the number of the last one in the original list, the next cycle, the sequence of the n-1, as a heap loop. The time complexity is also: O (NLOGN)Eight summaryIn fact, various algorithms, especially the latter three more complex

than D), but the cardinality sort is only suitable for a key code with distinct structural characteristics such as strings and integers. When n is large and d is small, it can be sorted by cardinality. (5The sorting algorithm discussed earlier, in addition to the Cardinal sort, the other sorting algorithm is the sequential storage structure. In order to avoid a significant amount of time to record movem

the three as the benchmark, before the Division starts, the benchmark record is exchanged with the 1st records of the region. The subsequent division process is identical with the preceding partition algorithm. 　　② Obtain the random number K (low ≤ k ≤ high) between low and high, and use R [k] as the reference.The best way to select a benchmark is to use a random function to generate a random number K (low ≤ k ≤ high) between low and high, and use R [k] as the benchmark, which is equivalent t

Summary of multiple sorting algorithms (not including detailed projections of complexity)Stable sorting and unstable orderingStable ordering: The relative position of the same element in the sort does not change.Unstable sort: The relative position of the same element in the sort is changed.Internal sorting and externa

// Several groups of identical random arrays to be sorted are used to test the efficiency difference between different sorting algorithms. # Define array_group_num 5 # Define round_num 6 void print_array (int * a, int Len ); Void print_array_link (int * a, int * link, int head, int endflag); int main (void) ...{ // The pointer array is used to point to several groups of sorted arrays with the same data. In

environment, the internal loop of the keyword Index program contains a large number of operations, which are much larger than the internal loops of a quick sort or merge sort algorithm. So the linear time overhead of the cardinality sort is not actually much smaller than the time overhead of fast sorting. And because the sorting code extraction algorithm based on the base sort is affected by the operating

efficient than insert sorting, when the amount of data is less, insert sort is more efficient*/functionswap (arr, index1, index2) {vartemp =ARR[INDEX1]; ARR[INDEX1]=Arr[index2]; ARR[INDEX2]=temp;}functionShellsort (arr) {varN =arr.length; varH = 1; Console.time (' Hill sort time-consuming '); while(H ) {h= 4 * H + 1; } while(H >= 1) { for(vari = h; i ){ for(varj = i; J >= H Arr[j] h) {Swap (arr, J, J-h); }} H= (h-1)/4;

This article turns from: The ten classic sorting algorithm, which has the dynamic Diagram + code detailed, this article simple introduction + personal understanding. Sorting algorithmsClassic algorithmic problems are also frequently asked questions during the interview process. The sorting algorithm is simply categorized as follows:The time complexity of these
