when you think about your impression of a home you've visited for the first time, what do you remember? the amount of light entering the rooms, the color of the furnishings and the size of the space tend to be the most memorable things, but you will have noticed the flooring even if you don’t rememb
floor math.sqrt number ; it is a prime. indeed, if n = a*b is composite with a and b ≠ then one of the factors a or b is necessarily at most square root of n.
say you want to allo e memory in chunks think: cache lines, disk sectors ; how much memory will it take to hold an integral number of chunks
we make a "wheel" with two positions on it, one half that "hits" on the even index 0 represents 3 // no need to zero above composites array; zeroed on creation for var i i ; function doit const limit = math.floor parsefloat document.
this is a bit shorter, not sure if it& 39;s what you are going for though // stub function const create composite = => math.floor math.random * 0

you can do this faster using a nearly optimal trial division sieve in one long line like this: enumerable.range 0, math.floor 2.52*math.sqrt num /math.
change lim to limit . of course you must have known that. since sieve = false *limit , the largest index allowed is limit- . however, on this line if n <= limit and

taking the advice of michael mior and poke, i wrote a solution. i tried to use a few tricks to make it fast. since we need a relatively short list of numbers tested,

oct 28, 20 3 since your program tests just one number, you& 39;re wasting time trying to avoid testing by composites. you perform a lot of computations to save

you need to check all numbers from 2 to n- to sqrt n actually, but ok, let it be n . if n is divisible by any of the numbers, it is not prime. if a number is prime, print
