# better_linear_search.py
#   This program uses a linear search of an array of size n for
#   value x but unlike its predecessor linear_search.py it does
#   not traverse the entire array regardless of value x being
#   discovered.  It simply returns the value immediately once
#   the value of x in found in the array.  If not found then it 
#   will just return text saying it wasnt found.

print(linear_search(things, 5, "cat")) # prints the index of "cat" which is 2
print(linear_search(things, 5, "hammer")) # prints the index of "hammer" which is 4
