Check whether one string is rotated version of other(Josh software programming test problem-2)

Write a program to accept two strings str1 and str2 and checks whether str2 is rotated version of str1.
Ex. Following are different values of str2 for given str1.
GIVEN:str1=”software”
2-character left rotate
str2=’resoft’
4-character left rotate
str2=’waresoft’
3-character right rotate
str2=’twaresof’

It seems to be bit difficult problem ,but it’s not actually. To solve this problem , We have to append first string to itself. And then check whether second string is present in first or not.

For example:
str1=”software”
str2=”resoft”
so append str1 to itself. Hence now str1=”softwaresoftware” . Now check str2 is present in str1 or not. Str2 is present in str1, hence str2 is rotated version of str1.

Note- You can not use strcat() function of string.h to concatenate a string to itself .Concatenation of string to itself using strcat() function is undefined behavior in C.

Solution using inbuilt  function of C.

 

Solution without using inbuilt functions

10 resons why I blog

Before I started my first blog, I have misconception that to start a blog we need lots of money and blogging  is difficult . Then my ex room mate Akash Nandnaware( who blog marathi poetry ) told me that ” you can start a free blog of your photos . Your blog will become famous, You can also earn money .” So very next day I opened my first blog all4photos.blogspot.com (now vphotoshop.com )on blogger.com. I started my blogging career on 24 July 2012 and now I am author of three blogs. Thank you Akash for suggestion .

Here are some reasons why I started blogging and I am still blogging!

Money is main reason to start blogging for me. And it’s every blogger’s dream to earn money from blog. But after some days I realized that we should not blog only for money .It’s not so easy to earn money through blogging. We have to do lot’s of hardwork

3.  Share my knowledge

I share my photoshop knowledge on vphotoshop.com and ImageDashboard.com. It’s not necessary that you should be expert to blog about. So start your blog today about things that you love and have some knowledge.

I love to help people. Blogging is great platform to help people and share your knowledge. A great thought by Zig Ziglar “You will get all you want in life if you help enough other people get what they want.”

5.  Stay updated

To write fresh content ,I should know what is happening in my industry so blogging  forces me to stay updated about what  I write.

I want to create my identity on internet because now days its not enough to have only offline identity and now internet is best way to reach large audience, to express your thought and share your knowledge.

7.  Improve english

Welcome to GauravVichare.com

Hi , Welcome to GauravVichare.com. I am feeling very lucky to have my website’s  name as my name. Because now days it’s very difficult to get own name as domain name. I grabbed this name in 2 days when I come to know that my name is available. It’s always good idea to buy YourName.com if you wanted to brand your name  or for other reasons.

It’s me
