问题描述:
输入两个递增的链表,合并这两个链表并使新链表中的结点仍然是按照递增排序的。
实现代码如下:
#include <stdio.h> #include <stdlib.h> #include <stdbool.h> struct List{ int date; struct List *next; }; struct List* doMergeList(struct List *P1head,struct List *P2head){ if(P1head==NULL) return P2head; else if(P2head==NULL) return P1head; struct List *mergeHead = NULL; if(P1head->date <P2head->date){ mergeHead = P1head; mergeHead->next=doMergeList(P1head->next,P2head); }else { mergeHead=P2head; mergeHead->next=doMergeList(P1head,P2head->next); } return mergeHead; } int main() { struct List *P1head=(struct List *)malloc(sizeof(struct List)); struct List *P2head=(struct List *)malloc(sizeof(struct List)); P1head->date=0;P1head->next=NULL; P2head->date=1; P2head->next=NULL; int i; struct List *P1Temp=P1head,*P2Temp=P2head; for(i=1;i<4;i++){ P1Temp->next=(struct List *)malloc(sizeof(struct List)); P1Temp->next->date=i; P1Temp->next->next=NULL; P2Temp->next=(struct List *)malloc(sizeof(struct List)); P2Temp->next->date=i*3; P2Temp->next->next=NULL; P1Temp=P1Temp->next; P2Temp=P2Temp->next; } P1Temp=P1head,P2Temp=P2head; printf("this is first list:\t"); while(P1Temp!=NULL){ printf("%d\t",P1Temp->date); P1Temp=P1Temp->next; } printf("\nthis is second list:\t"); while(P2Temp!=NULL){ printf("%d\t",P2Temp->date); P2Temp=P2Temp->next; } printf("\nthis is merge list:\t"); struct List *Head = doMergeList(P1head,P2head); while(Head!=NULL){ printf("%d\t",Head->date); Head=Head->next; } printf("\ndomerge done!\n"); return 0; }
