map

We have a list of numbers. Let's produce the double of every element.

(1) map
def main(): li = [8, 5, 1, 3] result = [2 * x for x in li] print(result)	import std.stdio; import std.algorithm; // map() import std.array; // array() void main() { int[] li = [8, 5, 1, 3]; int[] result = li.map!(x => 2 * x).array(); writeln(result); }

Output:

[16, 10, 2, 6]
