复习快速排序,用C语言实现: #include <stdio.h> int quicksort(int begin, int end, int a[], int len); void main() { , , , , , , , }; int len = sizeof(a)/sizeof(int); ; ; int pivot; pivot = quicksort(i, j, a, len); //printf("\npivot:%d\n", pivot); //for(i
//快速排序: #include <stdio.h> #define MAX 500000 int s[MAX]; void Q_Sort(int start,int end) { int i,j,t; if ( start >= end ) return ; t = s[start]; i = start; j = end; while ( i < j) { while ( s[j] >= t && i < j) { j--; } s[i] = s[j
