mystery$\_$string $="$my cat your cat"

#You may modify the lines of code above, but don't move them!

#When you Submit your code, we'll change these lines to

#assign different values to the variables.

#Add some code below that will count and print how many

#times the character sequence "cat" appears in mystery$\_$string.

#For example, for the string above, it would print $2.$

#

#This one is tricky! Think carefully about for$-$each loops,

#conditionals, and booleans. How can you track what character

#you're currently looking for? We expect you'll use a loop

#and a single big conditional, but there are other approaches

#as well. Try to stick with the topics we've covered so far.

#Add your code here!
