Master Kotlin Programming

A growing, hands-on Kotlin learning repository focused on programming fundamentals, data structures, and algorithmic thinking.

Get StartedTry Kotlin
main.kt
fun main() {
    // Welcome to Kotlin Educational
    val greeting = "Hello, Kotlin!"
    println(greeting)
    // Functional programming example
    val numbers = listOf(1, 2, 3, 4, 5)
    val doubled = numbers.map { it * 2 }
    println("Doubled: $doubled")
    // Higher-order function
    fun operation(x: Int, y: Int, op: (Int, Int) -> Int): Int {
        return op(x, y)
    }
    val sum = operation(10, 5) { a, b -> a + b }
    println("Sum: $sum")
}
