The time complexity is also the same as the above solutions. 6. Conclusion This article provided different ways to count the number of unique digits in an integer, along with their time complexities. The example code from this article can be foundover on GitHub....
Let f(k) = count of numbers with unique digits with length equals k. f(1) = 10, ..., f(k) = 9 * 9 * 8 * ... (9 - k + 2) [The first factor is 9 because a number cannot start with 0]. 代码如下: 1 2 3 4
