Basic Star Patterns — Swift

In the software Development interviews sometimes goes through the tasks of printing star patterns .And sometimes it seems too difficult perform these type of challenges about patterns . So here are some programs in Swift to print different patterns which might help into interview process.

Pattern 1: Square Star Pattern

Square star Pattern

func square(_ star : Int){
for i in 0...star {
print(String.init(repeating: "* ", count: star))
}
}
square(10)

Pattern 2: Triangle star Pattern

Triangle Star Pattern

func traingle(_ star : Int){
for i in 1...star
{
print(String.init(repeating: " ", count: star-i) + String.init(repeating: "*", count: 2*i - 1))
}
}
traingle(10)

Pattern 3: Reverse Triangle Star pattern

Reverse Triangle star pattern

func reverseTraingle(_ star : Int){
var i = star
while i >= 1{
print(String.init(repeating: " ", count: star-i) + String.init(repeating: "*", count: 2*i - 1))i = i--
}
}
reverseTraingle(10)

Pattern 4: Right Triangle Star Pattern

Right side Triangle

func rightTraingle(_ star : Int){
for i in 1...star{
print(String.init(repeating: " ", count: star-i)+String.init(repeating: "*", count: i))
}
}
rightTraingle(10)

Pattern 1 : Down Side Right Triangle Star pattern:

Down side triangle star Pattern

func downStarPattern(_ star : Int) {
for i in 0...star-1
{
print(String.init(repeating: "*", count: star-i))
}
}
downStarPattern(10)

Happy Coding :)
