How to print Diamond Pattern in Kotlin ?

Answer

To print a Diamond Pattern in Kotlin, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars to form the pattern.

✐ Examples

1 Diamond Pattern

In this example,

We define a variable n to represent the desired number of rows in the diamond pattern.
We use two nested for loops, where the outer loop runs from 1 to n and the inner loops control the spaces and stars in each row.
Within the inner loops, we calculate the number of spaces and stars based on the current row number to form the diamond pattern.

Kotlin Program

fun main() {
    val n = 5
    for (i in 1..n) {
        for (j in 1..n - i) print(' ')
        for (j in 1..2 * i - 1) print('*')
        println()
    }
    for (i in n - 1 downTo 1) {
        for (j in 1..n - i) print(' ')
        for (j in 1..2 * i - 1) print('*')
        println()
    }
}

Output
