题目：

[说明] 若S和T是用结点大小为1的单链表存储的两个串，试设计一个算法找出S中第一个不在T中出现的字符。查找过程是这样的，取S中的一个字符(结点)，然后和T中所有的字符一一比较，直到比完仍没有相同的字符时，查找过程结束，否则再取S中下一个字符，重新进行上述过程。[函数] typedef struct node {char data; struct node *next; }LinkStrNode; //结点类型typedef LinkStrNode *LinkString; //LinkString 为链串类型 LifikString S; //S 是链串的头指针 char SearchNoin ( LinkString S, LinkString T ) {//查找不在T中出现的字符 LinkStrNode *p, *q; (1) ; q=T; while ( (2) ) {//取S中结点字符 while( (3) )//进行字符比较 q=q-＞next； if(q==NULL) return (4) ；//找到并返回字符值 q=T；//指针恢复串T的开始结点 ( (5) )； } printf("there’s no such character.")； return NULL：}

Dog walkers provide a 20 to 60minute daily walk for a client's(客户)dog, making sure the dog

answers the call of nature and gets proper exercise. They often walk more than one dog at a time. Some

walkers work for dogwalking services, especially when starting out. Others have their own businesses,

and build by word of mouth and advertising. Dog walkers often work parttime, and some provide other

services like pet sitting or transporting.

In New York, dog walkers usually earn about $25 an hour. If you work for a dogwalking business,

you may earn less; if you are on your own dealing with several dogs at the same time, it may be more.

What do you have to do to be a dog walker?

First, have a real love of dogs, and have a good knowledge of how to get on with dogs. Try calling

dogwalking services to find out about openings. If you're on your own, you'll need to network and market yourself. You might advertise your services in pet offices, grooming businesses, or neighborhood papers.

You will need business cards and a mobile phone, and have good references and a clean background.

You'll also have to deal with taxes and insurance. You should be physically fit, friendly, neatly dressed

and extremely dependable. Many dog walkers are bonded(被担保的)and insured, and this is a definite

selling point to clients.

Of course, you will be cleaning up dog waste! You will also be outside in all kinds of weather. You

may have to deal with dogs that don't like each other, and difficult owners. It's also an upanddown kind

of business-clients can come and go.

For pet lovers, spending the workday with dogs instead of navigating office politics is its own reward! You are your own boss-you can dress casually, your doggy clients will love you unconditionally, and

you'll get some great exercise!
