Condense Whitespace

You are given a string containing multiple words separated by various whitespace characters (including spaces, tabs, and newlines). Your task is to write a program that reduces all consecutive whitespace characters to a single space and removes any leading or trailing whitespace.

Note: You must read the input from standard input and write the output to standard output.

For example, if the input is:

  hello   world  

then the output should be:

hello world

If the input is:

line1\n line2\t\tline3

then the output should be:

line1 line2 line3

inputFormat

outputFormat

Output a single line containing the string after condensing all consecutive whitespace characters to one space and removing any leading or trailing whitespace.## sample
