My name is Alexis and I was given a ditto in my Algebra I Honors class. There is one question that I understand but was wondering if there is an easy way to work the problem. The only way I know how to work it would take extremly too long. Here it is: In a string of numbers, two adjacent digits are considered as a two-digit number. For instance, the string 11012 contains the numbers 10, 11, and 12. What is the number of digits in the smallest string that contains all of the two-digit numbers from 10-99? Please help and thank you for any assistance you can give me. (I would also appreciate it if you would include an explanation on how the problem was solved)
