Write a function to extract the date patterns from a given text string. Don’t use any libraries (e.g date-extractor, spacy) to extract date. You can use datetime or similar libraries only to validate (not extract) the extracted date. Here are some example date formats for your reference:

1. OCT.04,2018
2. 19 September, 2018
3. 2018/9/20
4. 05.10.2016
5. 9th day of month February of year 2017
6. 18-OCT-2018
7. 23-Oct-18
8. Oct 17, 2018
9. 2018/10/23
10. 19th of September, 2018.

Note: Ensure only valid dates are extracted. For ex : 32/12/2019 is invalid
The function should handle variation in space, combination of (-.,/) and should be case insensitive
Hint: Use regex

Function format: extract_date(query_string) --> extracted_date_string
Function name: extract_date
Arguments: query_string (contains max 1 date)
Returns: date_extracted (type string)

You have a string of lowercase English alphabets. You can perform only two types of operations on the string:

1. Append a lowercase English alphabetic letter to the end of the string.
2. Delete the last character in the string. Performing this operation on an empty string results in an empty string.

Given an integer, k, and two strings, s and t, determine whether or not you can convert s to t by performing exactly k of the above operations on s.

Function format: is_convertible(k, s, t) --> boolean
Function Name: is_convertible
Arguments: k, s, t
Returns: boolean (True or False)

0 ≤ k ≤ 100
0 ≤ len(s) ≤ 100
0 ≤ len(t) ≤ 100

k=5
s=whoareyou
t=whoarewe

True

As we can delete (y,o,u) and add (w,e) in exactly 5 moves
if k=6 then output is False
If k=7 then out is True as we could delete (e,y,o,u) and add (e,w,e) in exactly 7 moves )
