If all decimal numbers are concatenated in a string then we will get a string which looks like string P as shown below. We need to tell Nth character of this string.
P = “12345678910111213141516171819202122232425262728293031….”
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. The first line of each test case contains the integer N.
Print the Nth character in the concatenated decimal string for each test case in a new line.
