'''Generating functions'''
<lang julia>function walk(maze, cell, visited = Any[])▼
push!(visited, cell)▼
if !(neigh in visited)▼
maze[round.(Int,(cell+neigh)/2)...] = 0▼
for neigh in shuffle(neighbors(nxtcell, size(maze)))
end
end
end
function maze(w::Int, h::Int)
firstcell = 2 * [rand(1:w), rand(1:h)]
return walk(maze, firstcell)
end</lang>
'''Printing functions'''
