Given a binary tree, flatten it to a linked list in-place. 将二叉树展开成链表 [ ] (D:\dataStructure\Leetcode\114.png) 思路:将根节点与左子树相连,再与右子树相连。递归地在每个节点的左右孩子节点上,分别进行这样的操作。 代码 Copy classSolution(object):defflatten(self, root):ifroot ==None:...
# converting the string to a set temp_set = set(my_string) # stitching set into a string using join new_string = ''.join(temp_set) print(new_string) 1. 2. 3. 4. 5. 6. 7. 8. 9. 5. 打印 n 次字符串或者列表 这个技巧通过乘法即可实现打印多次的操作: n = 3 # number of repe...

Special binary strings are binary strings with the following two properties: The number of 0’s is equal to the number of 1’s. Every prefix of the binary string has at least as many 1’s as 0’s. Given a special string S, a move consists of choosing two consecutive, non-empty, sp...
