Dice Pairs (2)

We want to run several experiments like those of the problem Dice Pairs (1).

In each experiment, we have been throwing a pair of dice repeatedly, recording the outcome.

Write a program that, for each of the experiments in a series of them, reads the sequence of outcomes of the experiment and prints out the histogram, under the same conditions as in Dice Pairs (1).

Input

Input is a sequence of experiments. Each experiment consists of the outcomes of the corresponding dice throws. The end of the data for each single experiment is indicated by a zero.

Output

Print the successive histograms corresponding to the successive experiments. After each histogram, print a line with five dashes.
