Accelerate C code

I want you to optimize the C code attached.

If you want this project, and before I give it to you, and *before I pay* you, you will have to

(1) download the file,

(2) optimize it, only pure C allowed, no C++, keeping the name of the variable as close as possible to the original code and making sure the optimized code produces the same output

(3) send me a chat message with what speedup you can achieve for inputs of different sizes and different levels of optimization (O1, O2, O3)

(4) if I believe and like your speedup, I will then, and only then, pay you in full

*After* I pay you, you will send me your code, a single file in pure C, no C++ If it does not meet the speedup claim you claimed in (3), then I will dispute the quality of your work and ask freelancer for a reimbursement.
