Optimized Prime Check Function (is_prime): This function includes additional checks: It returnsFalsefor numbers less than or equal to 1. It returnsTruefor the number 2. It returnsFalsefor even numbers greater than 2. It checks divisibility only for odd numbers starting from 3 up to the squar...
#define function isprime to check whether number P is prime or not #loop to generate the final result # parameter 's' stand for the index of moni prime number # parameter 'm' means the moni prime # when s=6 , the m=131071
This function does a quicker # prime number check before calling rabinMiller(). if (num < 2): return False # 0, 1, and negative numbers are not prime. # See if any of the low prime numbers can divide num: for prime in LOW_PRIMES: if (num == prime): return True if (num % ...
