Problem 115. Distance walked 1D
Suppose 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

Amitava, can you give a clearer idea of what your function inputs and outputs should look like?
If you leave one test the solution is simply 9. As is this submission is very poor.
Needs generalization and a larger test suite.
This is a pretty good idea for a problem but it's *very* poorly stated.
I cleaned up the problem statement and added a few more tests.
good idea...
Very good problem. I had to solve the same one to determine whether a signal was oscillating or stable.
Interesting problem
nice problem
