So far so good

But instead of printing you want to count heads
Do you know how to test if the result of your function is "HEADS"?
Do you know how to increment a counter - ie add one to it?
Do you know how to return that value from your function at
the end of the for loop?
You should do, because you have done something very
similar to 1 and 3 in your coinToss function.

Because its homework we won;t give you the answer just
some hints. Have another go and post the result if it doesn't
