Self-Locating Strings In Pi
January 4, 2019
[ I worked half-time during December, still suffering fatigue, then during the Christmas break I visited my daughter in Houston; I’m back at work full-time now. Thanks to all for your good wishes. ]
Numberphile has a short episode about self-locating strings in π; for instance, if you ignore the part before the decimal point and number the digits of π starting from zero, the sixth digit of π is 6 and the two digits starting at the 27th digit are 27.
Your task is to write a program that finds self-locating strings in π (A064810). When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
