[MATH CODING FOR FUN] Primitive root of unity mod P

How about making a code to calculate primitive roots of unity modulo P? Wanna give it a try? Definition of primitive roots of unity mod P: An integer A (1 ≤ A ≤ P–1) is a primitive root of unity (mod P) if A^K is not congruent to 1 (mod P) for 1 ≤ K ≤ P–2. (P is a prime number) For example, P=7 There are: 3^1 is 3(mod 7), 3^2 is 2(mod 7), 3^3 is 6(mod 7), 3^4 is 4(mod 7), 3^5 is 5(mod 7). 5^1 is 5(mod 7), 5^2 is 4(mod 7), 5^3 is 6(mod 7), 5^4 is 2(mod 7), 5^5 is 3(mod 7). So, it should be: INPUT: 7 OUTPUT: 3,5 I’m looking forward to seeing many people writing codes in many different languages for this topic. 😄 https://code.sololearn.com/c864moLa12x6/?ref=app
