I'm trying to find the shortest and best way to achieve the following:
Given input integer $N, get the following output:
- n = 0, output = 0
- n = 1, output = 0
- n = 2, output = 10
- n = 3, output = 100
- n = 4, output = 1000
- n = 5, output = 10000
I do this with the following code, but there must be a better option to do this.
<?php
$n = 1;
function getNumber($n) {
if ($n === 0 OR $n === 1) {
return "0";
} else {
return "1".str_repeat("0", $n -1);
}
}
echo getNumber($n);
?>
