Staircase

  • nemanja1 + 2 comments

    My solution: 

    let space = Character(" ")
let char = Character("#")

var spaceCount = 0
var charCount = 0

for (var i = 0; i<n; i++) {
    spaceCount = n-1-i
    charCount = i+1
    let spaceString = String(count: spaceCount, repeatedValue: space)
    let charString = String(count: charCount, repeatedValue: char)
    print("\(spaceString)\(charString)")
}

      Could you explain the "let" function (for lack of a better term)? Is it used in Python 2? I can't find an explanation of it online. Thank you!:)

        That's not Python it's Swift.

          Oh gotcha. Thanks!:D

      Mine was very similar, only real difference is that my for loop is ready for Swift 3... 

      var n = Int(readLine()!)!
for i in 1...n {
    var row = ""
    let spaces = n-i
    let hashes = n-spaces
    row += String(count: spaces, repeatedValue: Character(" "))
    row += String(count: hashes, repeatedValue: Character("#"))
    print(row)
}

        // Current Syntax Is

        for i in 1...n {
  var row = ""
  let spaces = n-i
  let hashes = n-spaces
  row += String(repeating: Character(" "), count: spaces)
  row += String(repeating: Character("#"), count: hashes)
  print(row)
}
