Lef counting aeries (n): he Champernowne word 1234567891011121314151617181920212223., also kno ounting series, is an infinitely long string of digits made up of all positive integers writ scending order without any separators. This function should return the digit at positio hampernowne word. Position counting again starts from zero for us budding computer se f course, the automated tester will throw at your function values of n huge enough that t onstruct the Champernowne word as an explicit string will run out of both time ands efore receiving the answer. Instead, note how the fractal structure of this infinite seque vith 9 single-digit numbers, followed by 90 two-digit numbers, followed by 900 t umbers, and so on. This observation gifts you a pair of seven league boots that allow the kip prefixes of this series in exponential leaps and bounds, instead of having to crawl th he desired position one step at the time with the rest of us. Once you reach the block umbers that contains the position n. the digit there is best determined with integer a erhaps aided by an str conversion for access to digit positions. Expected result
