- * 440. K-th Smallest in Lexicographical Order
- *
- * Given integers n and k, find the lexicographically k-th smallest integer in the range from 1 to n.
-
- Note: 1 ≤ k ≤ n ≤ 109.
-
- Example:
-
- Input:
- n: 13   k: 2
-
- Output:
- 10
-
- Explanation:
- The lexicographical order is [1, 10, 11, 12, 13, 2, 3, 4, 5, 6, 7, 8, 9], so the second smallest number is 10.
