LinkedList类表示Linked list本身,用head属性储存相对于第一个结点的reference和用add方法在结点的末尾添加新的结点。 总之,虽然list和linked list都是用于储存集合的元素,但是list是储存在连续的内存位置,可以用indices获取,但是linked list是储存在不同的结点位置,需要用结点之间的reference(指针)获取。 两数相加(addTw...
2.5 You have two numbers represented by a linked list, where each node contains a single digit. The digits are stored in reverse order, such that the 1’s digit is at the head of the list. Write a function that adds the two numbers and returns the sum as a linked list. EXAMPLE Inpu...
Add Two Numbers You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. Input:(2 -> 4 -> 3) + (5 -> 6 -> 4) Output:7 ->...
,也是一个linked lists。 这一运算过程,首先需要一个新的linked lists来储存运算结果,记为p,同时也需要一个s来判断是否有进位1,如果有,则需在下一位的运算中加上1,没有则加0。接下来则是每一位的计算,如果某一linked lists被遍历完了,则在接下来的遍历过程,该linked lists的元素参与加法的位置一直是None,比...
