Exercise 4 (a) Notice that, if we begin an AbsoluteProgression progression with 0 and 1 as its first values, the resulting progression has the following repeating pattern: 0,1,1,0,1,1,0,1,1,.... Define another progression that yields some repeating (but not the same) pattern for some initial values and implement it in a class named MyProgression, extending the class Progression. Your repeating pattern must not be a simple repetition of a single value. Also, your progression must clearly be distinct from AbsoluteProgression progressions. (b) In TestProgression.java, add a short code fragment to the class MyProgression. test Exercise 4 (a) Notice that, if we begin an AbsoluteProgression progression with 0 and 1 as its first values, the resulting progression has the following repeating pattern: 0,1,1,0,1,1,0,1,1,....
