RE: Weekend Challenge Sharpened: Missing Positions in Champernowne's Constant
Welcome back, nlj.
I'll do my best to answer your points: 1 Both. You have to deal with the necessary maths to know what to programme  You don't have to consider the proof that the number is normal. 2 My programme is the type of programme I really want, in principle the time taken is the same as the time needed for the powering operation. 3 Summation would be exclude but powering is OK, so is multiplication. I'm a bit primitive, & although multiplication is iterated addition & powering iterated multiplication I'd allow them, I guess basically through habituation & speed. I don't have a better answer than yours but you have displayed the best understanding of the problem & may have the best chance of finding a more timeflat solution (as it looks like no one else is bothered  where are the alternative solutions people!).
