let inputInt = Int(readline()!)!
let arrayInt = readlin()!.characters.split { $0== " " }.map { Int(String($0))! }
ex. https://atcoder.jp/contests/dp/tasks/dp_h
from fmhr
h, w = (int(i) for i in input().split())
2 4 5 7
would be
a, b, c, d = (int(i) for i in input().split())
turn it into an array
a = [int(i) for i in input().split()]
# a = [2, 4, 5, 6]
# or with a list
a = list(int(i) for input().split())
