First of all, I can give more proofs by testing from my end with different
haystacks / needles but I am not going to fix your benchmark issues.

I am only submitting my algorithm but you are putting extra work on me by
asking me to fix your benchmark issues. This is not my issue, this is the
issue of the person who designed and implemented the benchmark tests.

If you do like this, that is, if someone submits some work and then you ask
him to fix existing issues also then no one will be interested in
submitting their work because they may not want to fix your existing issues
in benchmark tests, etc.

Also, when I thought more, I realized that no one uses strstr() in real

C is now-a-days used only in embedded software / kernel, etc. and I have
programmed a lot in C but I don't ever remember using strstr().

You people think that you are the smartest people on this earth so let me
tell you something about myself.

1. I am programming since 1998.

2. I have programmed in C, C++, JAVA, PHP, PYTHON, HTML, PERL, JAVASCRIPT,

3. I had invented a new language and written its interpreter in 2002 when I
was an intern in a company.

4. I had written and published "How to implement system call". It can be
found here:

5. I have contributed many patches to linux kernel but left contributing
more when linux kernel developers became defensive.

6. I have worked in Cisco Systems and Juniper Networks in USA.

7. Currently, I am working for a networking company and writing code for 4G
/ 5G networks.

8. I have done B. Tech. in Computer Science from IIT - Varanasi after
getting a rank in IIT-JEE. IIT-JEE is one of the toughest exams in this

9. I have done Masters in Computer Networking from North Carolina State
University, NC, USA.
