Non-compatible function

[patricia-ternes]

In Data types/structures, when comparing list and dictionary, the functions do not give the same result.
So, we can not compare the execution time.

There is a simple fix. Change this

" if needle in haystack_dict: # time O(1) within dict\n",

to:

" if needle in haystack_dict.values(): # time O(1) within dict\n",

Problem: this solution makes dict solution worse.

Other solution is create the dict as the following:
haystack_dict = {value: key for key, value in enumerate(haystack_list)}
