// Find the nth digit of the infinite integer sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ...

//

// Note:

// n is positive and will fit within the range of a 32-bit signed integer (n < 231).

//

//

// Example 1:

//

// Input:

// 3

//

// Output:

// 3

//

//

//

// Example 2:

//

// Input:

// 11

//

// Output:

// 0

//

// Explanation:

// The 11th digit of the sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ... is a 0, which is part of the number 10.
