Consider an infinite string that consists of all positive integers in increasing order:
12345678910111213141516171819202122232425...
Your task is to process q queries of the form: what is the digit at position k in the string?
Input
The first input line has an integer q: the number of queries.
After this, there are q lines that describe the queries. Each line has an integer k: a 1-indexed position in the string.
Output
For each query, print the corresponding digit.
Constraints
- 1 \le q \le 1000
- 1 \le k \le 10^{18}
Example
Input:
3 7 19 12
Output:
7 4 1
