      Sieve of Eratosthenes: an ancient algorithm for finding all prime numbers up to any given limit. Make a list of all the integers ≤ n. Strike out the multiples of all primes ≤ √n, then the numbers that are left are the primes.pic.twitter.com/PXZ6Zgcd62

      In pseudo-code: Eratosthenes(n) { a[1] := 0 for i := 2 to n do a[i] := 1 p := 2 while p² < n do { j := p² while (j < n) do { a[j] := 0 j := j+p } repeat p := p+1 until a[p] = 1 } return(a) }

          Pretty nice way to interpret the algorithms of sieve of Eratosthenes into a coding language. It's a guide for math students and coders.

          Yes. JavaScript arrow functions and Java lambdas don't require parenthesis if there is only one argument. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions …
