Test run
./ is important.
By default, Linux won’t search the current
directory
for a program. So you have to
explicitly tell it
(eventually,
you can change your PATH environment
variable)
< means get the input from the file to the right
(inputs/maze1.txt),
instead
of the keyboard. If you don’t put this
in, runmaze will
expect
you to type the maze in on the keyboard – quite a hassle!
