#### Exercise 5: Matplotlib subplots

##### The solution of question 1 is accepted if 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 ?
