recursion_mystery8

Language/Type: PHP recursion recursion mystery

For each call to the following recursive function, write the output that is produced as it would appear on the console. Hint: To a re-tracing out long chains of calls, it may help you to look at your own notes on call results that you have already previously computed, and re-use those results as applicable. 

function recursion_mystery8($n) {
    if ($n <= 1) {
        print($n);
    } else {
        print("$n = (");
        recursion_mystery8(intval($n / 2) + $n % 2);
        print(", ");
        recursion_mystery8(intval($n / 2));
        print(")");
    }
}
recursion_mystery8(3);
recursion_mystery8(4);
recursion_mystery8(6);
recursion_mystery8(7);
