Now, as you see few solutions are very trivial. Lets generalise this and find all the numbers that can be written using three same numbers.
Consider all the even numbers (strictly less than 10) and denote them as 2m, m belongs to natural number. So all the numbers belongs to the following sets can be written using three same numbers.
, ,...etc.
Similarly, One can generate set of numbers that can be written using three same numbers using odd numbers (strictly less than 10) denoted by 2m+1
, ,... etc.
