Basic Star Patterns — Kotlin

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 Kotlin to print different patterns which might help into interview process. I have also provided the start Patterns in Swift language you can access those program here.

Pattern 1 : Horizontal line Star Pattern :

fun main() {
    for ( i in 0..5){
        print("* ")
    }
}

Pattern : 2 Vertical line Star pattern :

fun main() { 
    for ( i in 0..5){
        println("*")
    }  
}

Pattern 3 — Square Star Pattern :

fun main() { 
    var n = 5
    for ( i in 0 until n){
        for (j in 0 until n){
            print("* ")
        }
        println()  
    }  
}

Pattern — 4 Pyramid Star Pattern :

fun main() { 
    var n = 5
    for ( i in 0 until n){
        for (j in 0 until n-i){
            print(" ")
        }
        for (k in 0 until i){
            print("* ")
        }
        println(" ")  
    }  
}

Pattern — 5 Right angle Triangle Star Pattern :

fun main() { 
    var n = 5
    for ( i in 0 until n){
        for (j in 0 until n-1){
            print(" ")
        }
        for (k in 0 until i){
            print("* ")
        }
        println(" ")  
    }  
}

Pattern 6 — Rhombus Star Pattern :

fun main() { 
    var n = 5
    for ( i in n downTo 0){
        for (j in 0 until i){
            print(" ")
        }
        for (k in 0 until n){
            print("* ")
        }
        println(" ")  
    }  
}

Pattern 7 — Reverse Right angle triangle :

fun main() { 
    var n = 5
    for ( i in n downTo 0){
        for (j in i downTo 0){
            print("*")
        }
        println()  
    }  
}

Pattern 8 — Reverse Star Pyramid :

fun main() { 
    var n = 5
    for ( i in n downTo 0){
        for (j in n-i downTo 0){
            print(" ")
        }
        for (k in i downTo 0){
            print("* ")
        }
        println(" ")  
    }  
}

You can also access all of the patterns along with code gist from below link.

Happy coding 😊
