I will keep adding more FM’s as soon as i come across but i think above 4 FM’s mostly solve most of the requirements. Please share if you know any other FM’s with parameters to pass.

This blog is not to conflict any other blogs, there are many but i just thought to have all these at one place because requirements are different at different places.

Thank you.
