Apply TodaySuppose you go from position 7 to 10 to 6 to 4. Then you have walked 9 units of distance, since 7 to 10 is 3 units, 10 to 6 is 4, and 6 to 4 is 2. Total distance traveled = 3 + 4 + 2 = 9.

Example:

Input x = [1 2 3 2] Output y is 3

What's the wrong with this solution? It works perfectly on the Matlab R2015b.

The test suite expects the function's name to be 'your_fcn_name', instead of distanceWalked. (Which would have been a much more sensible name.)
