const fs = require('fs');
const input = fs.readFileSync("./dev/stdin").toString().trim().split("\n").map(v=>v.trim()); 
const N = +input.shift()

const answer = [...new Set(input)].sort((a,b)=>{
  if(a.length>b.length){
    return 1;
  }else if(a.length<b.length){
    return -1;
  }else{
    if(a>b){
      return 1;
    }else{
      return -1
    }
  }

console.log(answer.join('\n'))
