Anagram Groups

You are given a list of n strings. Your task is to group the strings into groups of anagrams. Two strings are anagrams if they contain the same characters in any order. In other words, strings s and t are anagrams if and only if
$$sorted(s)=sorted(t)$$

Each group should preserve the order of appearance from the input. Print each group on a new line with the words separated by a single space. Note that if there are no strings, you should output nothing.

Example: For input "eat tea tan ate nat bat", the anagram groups are:

• Group 1: eat tea ate
• Group 2: tan nat
• Group 3: bat

inputFormat

The first line contains an integer n denoting the number of strings.

The second line contains n strings separated by spaces.

outputFormat

Print the grouped anagrams. Each group must appear on a separate line with the strings in the same order as they appeared in the input, separated by a single space.
