Problems
Extra spaces
Extra spaces
Given a string. Write a program that will remove that line from all the extra spaces. A space will be assumed odd, if:
- He is at the beginning of the line, until the first word;
- it is in the end of the line after the last word;
- more spaces are located between two words (in other words, if the words are separated by more than one space, then all spaces except one - extra).
Input
Given a string S (0 ≤ |S| ≤ 255). The string contains only letters and spaces.
Output
Print a string without extra spaces.
