Create minimums_squares_to_represent_a_number.py (#7595) 
* Create minimums_squares_to_represent_a_number.py

added a dynamic programming approach of finding the minimum number of square to represent a number.
eg : 
25 = 5*5
37 = 6*6 + 1*1
21 = 4*4 + 2*2 + 1*1

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Update and rename minimums_squares_to_represent_a_number.py to minimum_squares_to_represent_a_number.py

updated the code

* Update minimum_squares_to_represent_a_number.py

I have added the appropriate checks for 0 and 12.34. 
It would be great if you could suggest a name for the dp array
