What is the difference between modular inverse and modular exponentiation?
Modular inverse is about finding a number that, when multiplied by another number, gives a product that is congruent to 1 modulo m. Modular exponentiation, on the other hand, is about finding the remainder when a number is raised to a power and then divided by another number.
