Bessie was daydreaming one day as she drifted between wakefulness and that delicious drowsiness that we all feel when we are tired. For a moment, she counted sheep as couldn't quite sleep. Bessie's mind is razor sharp and visualizes the numbers as she counts. She started noticing the digits and wondered: how many instances of each digit appear in a counting sequence?
Write a program to answer this question. Given two integers M and N (1 <= M <= N <= 2,000,000,000 and N-M <= 500,000), how many of occurrences of each digit appear?
Consider the sequence 129..137: 129, 130, 131, 132, 133, 134, 135, 136, 137. Count the digits to find:
1x0 1x5 10x1 1x6 2x2 1x7 9x3 0x8 1x4 1x9
1 10 2 9 1 1 1 1 0 1
