鸡尾酒排序

void sort(int arr[], int len){bool flag = true;int temp;while(flag){flag = false;int bottom = 0;int top = len - 1;int i;for(i=bottom; i < top; ++i){if (arr[i] > arr[i+1]){temp = arr[i];arr[i] = arr[i+1];arr[i+1] = temp;flag = true;}}--top;int j;for(j=top; j > bottom; --j){if (arr[j] < arr[j-1]){temp = arr[j];arr[j] = arr[j-1];arr[j-1] = temp;flag = true;}}++bottom;}}
