Count the Contractions in a Document

This problem requires you to count the number of contractions in a given document. A contraction is defined as any word that contains the apostrophe character ('). You will be given an integer n on the first line representing the number of lines in the document, followed by n lines of text.

Your task is to output a single integer which is the total count of words containing an apostrophe. For example, in the sentence "don't stop now", the word "don't" is counted as a contraction.

Note: The input will be read from stdin and the output should be printed to stdout.

inputFormat

The first line of input contains a single integer n indicating the number of lines in the document. The next n lines each contain a string potentially containing words with contractions.

Example:

3
don't stop now
I'll be there
we're not done yet

outputFormat

Output a single integer indicating the total number of contractions found in the document.

For the above example, the output should be:
