Description

Given $n$ strings containing some spaces, you need to remove all spaces from these strings and output the results.

Input Format

The first line contains a single positive integer $n$, indicating the number of strings ($1 \leq n \leq 10000$).
The next $n$ lines (from line 2 to line $n+1$) each contain a string (composed of uppercase letters, lowercase letters, and spaces).

Output Format

The output consists of $n+1$ lines. The first line contains a single positive integer representing the total number of spaces removed. Lines 2 to $n+1$ contain the $n$ strings after removing spaces (in the same order as input).
