Read a single sentence which terminates with a full stop(.). The words are to be separated with a single blank space and are in lower case. Arrange the words contained in the sentence according to the length of the words in ascending order. If two words are of the same length then the word occurring first in the input sentence should come first. For both, input and output the sentence must begin in upper case.
Examples
Test your program for the following data and some random data.
INPUT : The lines are printed in reverse order.
OUTPUT : In the are lines order printed reverse.
INPUT : Print the sentence in ascending order.
OUTPUT : In the print order sentence ascending.
