filter((c) => ! (2 : c-2).any((d) => c%d !(2:c-2).any((d)=>c%d!(2:c-2).any((d)=>c%d<1)).take(parseInteger(process.readLine()else"")else 0). Generate a list of primes based on your desired range, with each number separated by your preferred delimiter. filter by primality (using trial division) It also has a guide for learning the order the prime numbers come in. the infinite sequence of integers, starting with 2. This free, printable math chart lists the prime numbers between. The first two printable charts given below show the prime and composite numbers from 1-100. ~2> % if that gives more than two zeros: x is not prime: we need another iterationĬeylon, 93 bytes void p(Integer n)=>loop(2)(1.plus).filter((c)=>!(2:c-2).any((d)=>c%d Also amusing display charts which list the prime and composite numbers from 1 to 100 and extremely engaging activities like coloring, cutting, pasting and mazes are here for your children in grade 4 through grade 7. This is the current candidate for next prime, "x" T % duplicate top of the stack, which contains the latest found prime, "p" This runs n-1 times, to find the n-1 primes after 2 To test for primality a modulo operation is used: x is prime if computing mod(x,k) for k=1,2.,x produces no more than two zeros that is, if only two numbers of the set 1,2.,x divide x. The outer one produces each prime, and the inner one increases 1 by 1 from latest found prime until the next prime is found. This uses current release (10.1.0) of the language/compiler.
