Example 8.2: Digits of Pi, redux

In example 8.1, we considered some simple tests for the randomness of the digits of Pi. Here we develop a different test and implement it. If each digit appears in each place with equal and independent probability, then the places between recurrences of a digit should be Pr(gap = x) = .9^x * .1– the probability the digit recurs immediately is 0.1, the probability it recurs after one
