+$Part₁
+# the idea is to represent our position
+# as a complex number (2d vector). rotate by
+# 90 or -90 degrees when you encounter L or R
+# by multiplying by i or -i on the direction
+# vector. 
+# this can be done by folding with the initial
+# values i (direction) and 0 (position), pattern-
+# matching the next token on L or R and recognizing
+# them by ⍩.
+# once the direction vector has been rotated
+# accordingly, ⍥\+⋕ to add the direction unit vector
+# to the position vector n times for token Ln or Rn.
+# 
+# we can see many awesome pieces of functional and
+# array oriented code!
