Write a method that parses a list of directions and distances, returning a string that represents your net displacement from your starting position. The input parameter 'dirList' will contain a string of characters in the repeated form of "LN, " where L represents a letter N, S, E, or W indicating the direction of travel and N represents a single-digit number indicating how far you are traveling in that direction. Each time "LN" is followed by ", " EXCEPT for the last one. So "N3, S1, E5, E2, W1" represents going North 3 units, then South 1 unit, then East 5 units, then another 2 units, then going West 1 unit. This would place you 2 units North of your starting position and 6 units East of your starting position, so you return "N2 E6". Note: If your final displacement in the North-South direction is zero, report that as N0. If your final displacement in the East-West direction is zero, report that as E0. Look at the test data for further examples. Note that 'dirList' will contain at least one direction and amount.
