A single positive integer i is given. Write a program to find the digit located in the position i in the sequence of number
groups S1S2…Sk. Each group Sk consists of a sequence of positive integer numbers ranging from 1 to k, written one after
For example, the first 80 digits of the sequence are as follows:
The first line of the input file contains a single integer t (1 ≤ t ≤ 10), the number of test cases, followed by one line for
each test case. The line for a test case contains the single integer i (1 ≤ i ≤ 2147483647)
There should be one output line per test case containing the digit located in the position i.
