+     * 
+    --- Day 3: Spiral Memory ---
+
+    You come across an experimental new kind of memory stored on an infinite two-dimensional grid.
+
+    Each square on the grid is allocated in a spiral pattern starting at a location marked 1 and then counting up while spiraling outward. For example, the first few squares are allocated like this:
+
+    17  16  15  14  13
+    18   5   4   3  12
+    19   6   1   2  11
+    20   7   8   9  10
+    21  22  23---> ...
+
+    While this is very space-efficient (no squares are skipped), requested data must be carried back to square 1 (the location of the only access port for this memory system) by programs that can only move up, down, left, or right. They always take the shortest path: the Manhattan Distance between the location of the data and square 1.
+
+    For example:
+
+        Data from square 1 is carried 0 steps, since it's at the access port.
+        Data from square 12 is carried 3 steps, such as: down, left, left.
+        Data from square 23 is carried only 2 steps: up twice.
+        Data from square 1024 must be carried 31 steps.
+
+    How many steps are required to carry the data from the square identified in your puzzle input all the way to the access port?
