LeetCode刷题笔记---Add Two Numbers 最近开始刷LeetCode,为了以后的工作做准备。 1. Add Two Numberes 题目要求:输入两个链表,分别为: l1 : 2 >- 4 >- 3 l2 : 5 >- 6 >- 4 要求输出结果为: l3 : 7 >- 0 >- 8 分析:通过观察可以发现,其实就是从左向右对应位置相加,如果大于10,就像右进...
1. 分别使用/和%来代表进位符号flag和当前位的值value 2. 成立哑结点(头结点),这样可以方便很多。 Python代码 #Definition for singly-linked list.#class ListNode(object):#def __init__(self, x):#self.val = x#self.next = NoneclassSolution(object):defaddTwoNumbers(self, l1, l2):""":type l1...
//不创建新链表,直接把结果存到l1上,并对多出来的部分做"嫁接"处理//Runtime: 112 ms, faster than 99.52% of JavaScript online submissions for Add Two Numbers.varaddTwoNumbers2 =function(l1, l2) { let dummy= { next: l1 },//结果链表的head指针tail = dummy,//tail总是指向l1的前继元素(也...
(2)格式:对于变量来说,格式为:putchar(ch);对于常量来说,格式为:putchar(‘ch’),对于转义字符来说,格式为:putchar(’\n’)。 sprintf()做字符串拼接 难度指数:2颗星 / 细节指数:2颗星 / 重要指数:4颗星 字符串的处理一直是很重要的问题,C语言中的字符串拼接又不像Python里面直接一个加号就能解决的。
