int num = scan.nextInt();
if ((num > 0) && (num <= 15)) {
String s = "X".repeat(num) + "\n";

If this is a true or false question the answer is true.
First we need to understand what "n for n in range(10)" means. Basically, we are iterating through all the values n that are in the range of 10 (meaning 0, 1, 2, 3, ..., 9).
Next we are evaluating if n%2. The percentage sign is used to represent modulus which is the remainder of when two numbers are divided. In this case, we are dividing n by 2, and the remainder is our result. When dividing by 2, the only possible remainders are 0 or 1, which when used in an if statement represent the boolean vlaues false and true, respectively. We are doing this calculation for each n from 0 to 9, and if the result is true, we output n to an array.
The numbers that will result in true (a remainder of 1) are the odds numbers. For example, 4/2 = 2 with nothing left over while 5/2 = 2 with 1 left over.
So the following is returned:
[1, 3, 5, 7, 9]
