Consider the following method:

public int countPs(String word)
{
int sum = 0;
for(int i = 0; i < word. length(); i++)
{
word = word. toLowerCase();
if(word. substring(i, i+1).equals("p"))
{
sum++;
}
}
return sum;
}

What would the value of sum be after the method call countPs("Peter Piper picked a pack of pickled peppers")?
