You need to write a function taking 2 strings as input and returning True if the strings are anagrams and False otherwise.
Two strings are anagrams if they contain exactly the same letters in a possibly different order.
Eg : "abc" and "cab" are anagrams, "aab" and "bba" are not

Here you will need to write an algorithm that determines if a string is properly parenthesized, ie it is of the form "(p)" or "pq" where p and q are properly parenthesized strings. Any string (including the empty string) that does not contain any parenthesis is properly parenthesized.
Eg : "()()" is properly parenthesized, "(()" is not

For this one you will need to find the shortest path in a maze from a start to an end. The maze is represented by a matrix (more exactly a list of lists) containing only 0 and 1 - 0 is a wall, 1 is a path.
Every coordinate in the maze is represented by a tuple (x, y) where x and y are the indices of the point in the list of lists. This function should return a list of points forming the shortest_path in the maze [(x1, y1), (x2, y2), ...] between start and end, or False if there is no path.
The only movements allowed are UP/DOWN/LEFT/RIGHT

Matrix contiguous regions (cf. e.g. https://en.wikipedia.org/wiki/Flood_fill)

"Smallest positive integer"

Find the smallest "missing" integer in a list of integers. The list can contain both negative and positive integers. One integer can occur several times.
