This isn't a homework question. You guys are smart so I was wondering if you could somehow figure out the mysterious function f based on a few examples:
f(26134914) = 2085386485 f(26288902) = 2085920342 f(26289423) = 2094236422 f(26356300) = 2086136115 What is "f" doing to convert that 8 digit number to a 10 digit? I'll produce more examples if needed Thanks for the help

Do you understand that there exist an infinite number of functions that will give those specific numbers? And no matter how many more example you give, there always exist a infinite number of functions that will give any finite set of specific values.
