Is there a better way of getting this result? This function fails if num has more digits than digits, and I feel like it should be in the library somewhere (like Integer.toString(x,"%3d") or something)

```
static String intToString(int num, int digits) {
StringBuffer s = new StringBuffer(digits);
int zeroes = digits - (int) (Math.log(num) / Math.log(10)) - 1;
for (int i = 0; i < zeroes; i++) {
s.append(0);
}
return s.append(num).toString();
}
```

String.format (https://docs.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html#syntax)

In your case it will be:
