2강 20:28초에서 설명하고 있는 최적화 방법에 관하여

<pre><code>

 최적화
 보석값 입력 받기
let gem = readLine().map { Double($0)! }!


//소인수 분해해야함.
var answers: [Int] = []
var previous = Int(gem)
var squreRoot = Int(Double(gem).squareRoot())

func check2(divided: Int, i: Int) -> Bool {
 if divided % i == .zero {
 previous = divided / i
 answers.append(i)
 return true
 } else {
 return false
 }
}
//2,3,4
for i in 2...squreRoot {
 var flag = true
 repeat {
 let result = check2(divided: previous, i: i)
 flag = result
 } while flag
}

if previous != 1 {
 answers.append(previous)
}


answers.sort()
print(answers.count)
print(answers.compactMap { String($0) }.joined(separator: " "))</code></pre>통과한 답변 공유합니다~
