int PyList_SetItem(PyObjectlist, Py_ssize_t index, PyObjectitem) 设置别表指定位置的值,下标的所在的位置必须是有值的,并且是有效的 void PyList_SET_ITEM(PyObjectlist, Py_ssize_t i, PyObjecto) 和PyList_SetItem一样,但是就是没有错误检查 int PyList_Insert(PyObjectlist, Py_ssize_t index, ...
To build a max-heap from any tree, we can thus start heapifying each sub-tree from the bottom up and end up with a max-heap after the function is applied to all the elements including the root element. In the case of a complete tree, the first index of a non-leaf node is given...
# Bucket Sort in Python def bucketSort(array): bucket = [] # Create empty buckets for i in range(len(array)): bucket.append([]) # Insert elements into their respective buckets for j in array: index_b = int(10 * j) bucket[index_b].append(j) # Sort the elements of each bucket...
index() — Search for character inet6_is_srcaddr() - Socket address verification inet6_opt_append() — Add an option with length "len" and alignment "align" inet6_opt_find() — Search for an option specified by the caller inet6_opt_finish() — Return the updated total length ...
,"4",'5","6","7","8","9","10"}值得注意的是strArr3的长度不能 小于 index + strArr1.LengthSort排序这个方法不是数组对象的方法，而是Array提供的一个静态方法。int[] arr1 = new[] {1, 9, 28, 5, 3, 6, 0, 12, 44, 98, 4, 2, 13, 18, 81, 92}; Array.Sort(arr1);//0...

str.indexOf(searchStr,startIndex) searchStr必选,表示需要匹配的字符串值; startIndex可选,取值范围0到str.length-1,省略则默认首字符开始检索。 lastIndexOf() 返回指定字符串值最后出现的位置,在一个字符串中的指定位置从后向前搜索。 str.lastIndexOf(searchStr,startIndex) searchStr必选,表示需要匹配的字符...
list.pop([index=-1])——移除列表中的一个元素(默认最后一个元素),并且返回该元素的值 list.remove(obj)——移除列表中某个值的第一个匹配项 list.reverse()——反向列表中元素 list.sort( key=None, reverse=False)——对原列表进行排序 list.clear()——清空列表 ...
