The size of theHashSetafter iteration gives us the count of unique digits. The time complexity of this solution isO(n), wherenis the number of digits in the integer. Adding to aHashSetand checking its size are bothO(1)operations, but we still have to iterate through each digit. 4. Usi...

Use std::to_string and std::string::size Functions to Count Number of Digits in a Number in C++ 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 cou...
Given a non-negative integer n, count all numbers with unique digits, x, where 0 ≤ x < 10n. Example: Given n = 2, return 91. (The answer should be the total numbers in the range of 0 ≤ x < 100, excluding[11,22,33,44,55,66,77,88,99]) ...
