Compass, Map and Spyglass

Let's just take things one step at a time. For starters, you need to find a compass, map and spyglass to navigate the terrain. Hurry up! The nature is very unpredictable and if you don’t pick up those things in time, they will be absorbed by the coastal sand or washed away into the sea.
Your task is to count the sum of the number of steps required to pick up all 3 items - ('C' - compass), ('M' - map), ('S' - spyglass) from your starting position. So the result will be the sum of distance from Y to C, from Y to M and from Y to S (not Y-C-M-S).
Note that you can walk in 8 directions - left, right, up, down and sideways (on the diagonal in any direction). Your starting position is 'Y'.

Input: Array with the objects placements.
Output: The length of the path.
Example:
navigation([['Y', 0, 0, 0, 'C'], [ 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0], ['M', 0, 0, 0, 'S']]) == 11 #4 steps from Y to C, 4 from Y to S and 3 from Y to M
How it is used: For the finding the length of the path.
