How often does a word appear in a text?

Input

A line containing a word, followed by a line containing a text.

Output

The number of occurrences of the word in the text. Capitals and lower case letters may both be used, and you have to consider that the word should be a separate word, and not part of another word.

Tip

If you did the exercises from this chapter, you already developed a function that “cleans” a text. Combining that function with the split() function more or less solves the problem for you.
