Seventeen stones are arranged in a straight line. They are counted from left to right as $1, 2, 3, \ldots, 17$, and then from right to left, so that the stone previously counted as 16 is counted as 18. The pattern is continued to the left until the stone previously counted as 1 is counted as 33. The pattern then reverses so that the stone originally counted as 2 is counted as 34, 3 as 35, and so on. If this counting continues in the same manner, which of the original stones is counted as 122? Express your answer as a single digit which corresponds to the first digit assigned to that stone.

Present the answer in LaTex format: \boxed{Your answer}
