the following function, hasFourHs is supposed to return to True if there are at least 4 'H's in the parameter astring. There are three logic errors in the code. Explain what each error is,then show how to fix the function so it works as intended.

def hasFourhs(astring):

count = 0

for ch in astring:

if astring == 'H':

count = count +1

if count < 4:

return True

else:

return False
