This problem combines the decorator pattern with the CoR implemented in Problem 1. The text appearing in the output field of the LCP UI is a string that has to undergo three decorations: Round output to 2nd decimal (e.g., 218.723 to 218.72) Write output in exp. notation (e.g., 218.72 to 2.1872e2) Add the unit name to the converted amount (e.g., 2.1872e2 to 2.1872e2 Yards) Length Converter 0.2 Klometer 2.1872e2 Yards Yard The resulting processing flow (including the chain of responsibility from the previous problem) forLCPis shown sehematicelly in the next figure.
