Get rid of ugly if statements

How about such approach:

int getSize(int v) {
    int[] thresholds = {145, 117, 68, 51, 22, 10};

    for (int i = 0; i < thresholds.length; i++) {
        if (v > thresholds[i]) return i+1;
    }
    return 1;
}

Functionally: (Demonstrated in Scala)

def getSize(v: Int): Int = {
  val thresholds = Vector(145, 117, 68, 51, 22, 10)
  thresholds.zipWithIndex.find(v > _._1).map(_._2).getOrElse(0) + 1
}
