Aprogrammer wants to write a procedure that calculates the net elevation - total number of feet a traveler goes up and down. for example, looking at the first 3 segments of travel, the net elevation is 7 feet (up 3, up 1, down 3). write procedure (in either javascript or pseudocode) called processpath(data) that: accepts a list of elevation data as a parameter for every value in the list compute the absolute difference between that value and the value next to it on the path add the difference to a running total return the total elevation traveled in writing your procedure you should assume that you can call a function called absdiff(a, b).
