paizaラーニングレベルアップ問題集の【条件分岐メニュー】をやってみた (1)

paizaラーニングレベルアップ問題集の【条件分岐メニュー】をやってみました。

問題
単純な条件分岐

数値の分岐

数値演算結果で分岐

ゼロ以外

0が含まれていないか判定

方針
  • 最初の3問はコチラと同じです
  • if文を使ったコードと三項演算子を使ったコードを掲載します
  • 最終問題は$0$が入力された時点でNOを出力してプログラムを終了する方法もありますが、一応、入力は全て読み込みたいと思います
    • が、読者諸賢におかれましては、本当に「全て読み込」まれているか、ご確認いただきたいと思います。例えば 
      ans = ans && (int(input()) != 0)
      の様なコードでは、変数ansが既に偽の場合、int(input())の評価はされません。即ち、入力が読み込まれません

単純な条件分岐
let s = readLine()!
if s == "paiza" {
	print("YES")
} else {
	print("NO")
}

print(readLine()! == "paiza" ? "YES" : "NO")
数値の分岐
let n = Int(readLine()!)!
if n <= 100 {
	print("YES")
} else {
	print("NO")
