Read the entire input one line at a time and then output the largest line (according to the usual sorted order on Strings) followed by the largest line that occurs after the last occurrence of the largest line, followed by the largest line that occurs after that one, and so on. (Note that you will always output the last input line.) For example, if your lines contain 4, 2, 7, 9, 0, 8, 7, 8, 4, 3, 6, 3 then your output should be the lines containing 9, 8, 6, 3 since 9 is the largest value, 8 is the largest among {0,8,7,8,4,3,6,3}, 6 is the largest among {4,3,6,3}, and 3 is the largest and only value in {3}.

Can i get help with this code?Please do not answer if you do not know it.thanks
