Modify the display method of the LastDigitDistribution class of Worked Example 9.2 so that it produces a histogram, like this:
0: *************
1: ******************
2: *************
Scale the bars so that widest one has length 40.

Data from Example 9.2,

n this Worked Example, we investigate properties of number sequences. A number sequence can be a sequence of measurements, prices, random values, or mathematical values (such as the sequence of prime numbers). There are many interesting properties that can be investigated. For example, you can look for hidden patterns or test whether a sequence is truly random. Problem Statement Investigate how the last digit of each value is distributed. For a given sequence of values, produce a chart such as

0: 105
1: 94
2: 81
3: 112
4: 89
5: 103
6: 103
7: 100
8: 108
9: 105
