//Read 2D Array of Int 5x5
var arr : [[Int]] = Array(repeating: Array(repeating: 0, count: 6), count: 6)
for i in 0...5 {
  arr[i] = readLine()!.characters.split(separator: " ").map{ Int(String($0))! }
}

//Read Number
let mealCost = Double(readLine()!)!
//Read Int
let tipPercent = Int(readLine()!)!
let string = String(readLine()!)

// Read array of int with n elements with " " separated - Swift 3.0
var d = Int(readLine()!)!
var arr =  readLine()!.components(separatedBy: " ").map{ Int($0)! }

//Print Array with " " separator
for i in arr {
    print(i, terminator: " ")
}
