Problem Statement

Take a string and repeat it some number of times.
Example: repeat("ha", 5)   =>   "hahahahaha" If there is a simpler/more efficient way to repeat a single “character” (i.e. creating a string filled with a certain character), you might want to show that as well (i.e. repeat-char("*", 5) => "*****").

Let's start with the solution:

import std.stdio, std.array;

void main() {
    writeln("ha".replicate(5));
}


import std.stdio;

void main() {
    char[] chars;     // create the dynamic array
    chars.length = 5; // set the length
    chars[] = '*';    // set all characters in the string to '*'
    writeln(chars);
}
