We have to count all numbers with unique digits x, where x is in range 0 to 10^n. So if the number n is 2, then the result will be 91, as we want to find numbers from 0 to 100 without 11, 22, 33, 44, 55, 66, 77, 88, 99. To solve this, we will follow these steps...
The most straightforward way to count the number of digits in a number is to convert it to the std::string object and then call a built-in function of the std::string to retrieve a count number. In this case, we implemented a separate templated function countDigits that takes a single ...
