#### Exercise 5: Matplotlib subplots

###### For question 1, does the plot reproduces the plot in the image and respect those criteria?

###### Does it contain 6 subplots (2 rows, 3 columns)?

###### Does it have space between plots (`hspace=0.5` and `wspace=0.5`)?

###### Do all subplots contain a title: `Title i`?

###### Do all subplots contain a text `(2,3,i)` centered at `(0.5, 0.5)`? _Hint_: check the parameter `ha` of `text`.

###### Have all subplots been created in a for loop?
