The method returns the mergedList at the end.Using the main() method, we demonstrate the use of mergeLists() by passing two lists of integers (numbers1 and numbers2) and two lists of strings (words1 and words2). We merge the elements of each pair of lists and print the merged lists...
Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. 两个排好序的链表拼接,只要用两个指针遍历链表即可. 可以借助一个helper指针来进行开头的合并。如果有一个遍历完,则直接把另一个链表指针之后的部分全部接...
Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. 分析:合并两个有序序列,这个归并排序中的一个关键步骤。这里是要合并两个有序的单链表。由于链表的特殊性,在合并时只需要常量的空间复杂度。
