Typing Game

You're in the midst of creating a typing game.

Create a function that takes in two lists: the list of user-typed words, and the list of correctly-typed words and outputs a list containing 1s (correctly-typed words) and -1s (incorrectly-typed words).

# Inputs:

User-typed: ["cat", "blue", "skt", "umbrells", "paddy"]

Correct: ["cat", "blue", "sky", "umbrella", "paddy"]

 

# Output: [1, 1, -1, -1, 1]

Examples

correct_stream(

  ["it", "is", "find"],

  ["it", "is", "fine"]

) ➞ [1, 1, -1]

 

correct_stream(

  ["april", "showrs", "bring", "may", "flowers"],

  ["april", "showers", "bring", "may", "flowers"]

) ➞ [1, -1, 1, 1, 1]
