Sample case — your program reads stdin and prints to stdout.

Given an array of strings, group the anagrams together. Anagrams are words with the same characters in different order.

Algorithm: Sort each word's characters and use as key in a hash map.

Example: ['eat','tea','tan','ate','nat','bat'] → Groups: ['eat','tea','ate'], ['tan','nat'], ['bat']

Input format Line 1: n (number of words). Line 2: n space-separated words.

Output format Each group on a line, words space-separated, groups sorted alphabetically by first word, words within groups sorted.

Constraints 1 ≤ n ≤ 10⁴, 0 ≤ word.length ≤ 100, words are lowercase letters

Every problem you solve becomes a story you can tell in an interview.

Solving under pressure trains the muscle that's most tested in onsite rounds.
Explaining your approach out loud matters more than reaching the optimal solution.
Consistency wins: 1 challenge daily > 10 challenges on one Saturday a month.

Pro tip:After solving, write 2 lines on what you learned — that's what you'll remember in the interview.
