How to get the median of two sorted arrays in Kotlin

Answer 1

fun findMedianOfTwoSortedArrays(arr1: IntArray, arr2: IntArray): Double {
    val merged = (arr1 + arr2).sorted()
    val mid = merged.size / 2

    return if (merged.size % 2 != 0) {
        merged[mid].toDouble()
    } else {
        (merged[mid - 1] + merged[mid]).toDouble() / 2
    }
}

fun main() {
    val arr1 = intArrayOf(1, 3, 5)
    val arr2 = intArrayOf(2, 4, 6)

    val median = findMedianOfTwoSortedArrays(arr1, arr2)
    
    println("Median: %.1f".format(median))
}
