WebA primality test is an algorithm for determining whether an input number is prime.Among other fields of mathematics, it is used for cryptography.Unlike integer factorization, primality tests do not generally give prime factors, only stating whether the input number is prime or not.Factorization is thought to be a computationally difficult problem, whereas primality … WebNov 27, 2015 · Basically, you have an array of booleans called something like isPrime, and you mark off all of the numbers that are factors of something. Then you just go to the array index representing the value you want to check, and you get your answer pretty damn quick. So isPrime[3] == true and isPrime[9] == false. ryan weaver grunt style
