Counting Satisfying Elements

You are given an array of integers and a predicate condition. Your task is to count the number of elements in the array that satisfy the given condition.

The predicate condition is provided as a string and can be one of the following:

• even: Count numbers that are even. An integer \( n \) is even if \( n \mod 2 = 0 \).
• odd: Count numbers that are odd. An integer \( n \) is odd if \( n \mod 2 \neq 0 \).
• positive: Count numbers that are greater than zero.

Read the input from stdin and output the result to stdout.

inputFormat

The first line contains an integer \( n \), the number of elements in the array.

The second line contains \( n \) space-separated integers.

The third line contains a string which represents the predicate condition (even, odd, or positive).

You should read from stdin.

outputFormat

Output a single integer which is the count of numbers in the array that satisfy the specified condition. Write the answer to stdout.
