1. 키보드 입력 keydown 이벤트

   window.addEventListener("keydown", (e) => {
     const key = document.getElementById(e.key);
     if (key) key.classList.add("pressed");
   });
   

   • e.key로 누른 key값을 알아낼수 있다.

2. svg html 에서 그리는법

     <svg height="250" width="200" class="figure-container">
             <!-- Rod -->
             <line x1="60" x2="140" y1="20" y2="20" />
             <line x1="140" x2="140" y1="20" y2="60" />
             <line x1="60" x2="60" y1="20" y2="230" />
             <line x1="20" x2="100" y1="230" y2="230" />
   
             <!-- Head -->
             <circle cx="140" cy="80" r="20" />
   
             <!-- Body -->
             <line x1="140" x2="140" y1="100" y2="160" />
   
             <!-- Arms -->
             <line x1="140" x2="120" y1="110" y2="130" />
             <line x1="140" x2="160" y1="110" y2="130" />
   
             <!-- Legs -->
             <line x1="140" x2="120" y1="160" y2="180" />
             <line x1="140" x2="160" y1="160" y2="180" />
           </svg>
   

3. arr.prototype.find()

   • 주어진 판별함수를 마족하는 첫번쨰 요수의 값을 반환

   • 그런 요소가 없다면 undefined를 반환합니다.

   • const found = array1.find((element) => element > 10);
     

   • arr.find(callback[, thisArg])
     

solution

import sys
from functools import reduce
from collections import Counter
n = int(input())
arr = list();
for _ in range(n):
    t = int(sys.stdin.readline().strip("\n"))
    arr.append(t);
sum = reduce(lambda x,y:x+y ,arr)
print(round(sum/n))
arr.sort()
print(arr[n//2])
r3 = Counter(arr).most_common();

if len(r3) >1 and r3[0][1] == r3[1][1]:
    print(r3[1][0])
else:
    print(r3[0][0])
print(max(arr)-min(arr))
