In Worked Example 9.2, make the process method a default method of the Sequence interface.

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
