Kotlin function: Print asterisk pattern

Last update on December 20 2024 13:11:01 (UTC/GMT +8 hours)

Write a Kotlin function that prints a pattern of asterisks based on a given size. The size represents the number of rows and columns in the pattern. Use a single-expression function.

Sample Solution:

Kotlin Code:

fun printPattern(size: Int) = repeat(size) { println("*".repeat(size)) }

fun main() {
    val patternSize = 5
    printPattern(patternSize)
}

Sample Output:

*****
*****
*****
*****
*****

Explanation:

In the above exercise -

• The "printPattern()" function takes an integer parameter size, representing the number of rows and columns in the pattern.
• The "repeat()" function repeats the specified block of code size times. In each iteration, the code block is executed.
• Within the code block, the println function is called to print a string of asterisks. The repeat function is used to repeat the asterisk character size times.
• The printPattern function is called in the main function with a sample pattern size of 5.
• Finally the asterisk pattern is printed to the console.

Previous: Check if the number is negative.
Next: Add two numbers with an explicit return type.
