shellsort函数c语言shellsort函数c语言 在计算机科学中,排序算法是基础且重要的组成部分。Shell排序由DonaldShell于1959年提出,它是对插入排序的改进版本,通过将原始数据分割成多个子序列进行预处理,最终实现整体有序。这种排序方法的核心在于间隔序列的选取,常见的有Hibbard间隔序列、Sedgewick间隔序列等。以下将详细探讨...
/** 希尔排序** 参数说明:* a -- 待排序的数组* n -- 数组的长度*/voidshell_sort1(inta[],intn){inti,j,gap;// gap为步长,每次减为原来的一半。for(gap=n/2;gap>0;gap/=2){// 共gap个组,对每一组都执行直接插入排序for(i=0;i<gap;i++){for(j=i+gap;j<n;j+=gap){// 如果a[...
shell sort的C语言代码如下: void shellsort(int v[], int n) { int gap, i, j, temp; for(gap = n/2; gap > 0; gap /= 2) for(i = gap; i < n; i++) for(j = i - gap; j >= 0 && v[j] > v[j+gap]; j-= gap) { temp = v[j]; v[j] = v[j+gap]; v[j+...

C programs are smaller and faster then any other program created in a different language. C程序你其它任何不同语言产生的程序都要更小更快。 article.yeeyan.org 2. Remember that, just as shell can't replace all your C programs, the gst-launch tool can't replace a full GStreamer application....
