Count the Occurrence of a Digit

You are given a number n represented as a string, and a single digit d (also given as a string). Your task is to count the number of times the digit d occurs in the string representation of n.

Note: The input is provided via standard input (stdin) with n on the first line and d on the second line. The output should be printed to standard output (stdout) as a single integer.

For example:

Input:
123456789
3
Output:
1

The problem tests your ability to handle string manipulation and counting specific characters efficiently.

inputFormat

The input consists of two lines. The first line contains the string n representing the number. The second line contains the single digit d that you need to count in n.
Constraints: n can be a large number and may include leading zeros.

outputFormat

Output a single integer indicating the number of times the digit d appears in the string n.
