efficient use of modulus??

How to use modulus operations efficiently properly in functions containing large multiplication and power operations??

Be more specific.

Give an example of what you want to do.

I don’t understand what exactly you mean.

But picking up keywords- efficient, large multiplication, power modulus, i think what you are looking for is Exponential by squaring.
