How to sort each row from a two-dimensional array in Kotlin

Answer 1

fun sortRows(arr2D: Array<IntArray>) {
    for (row in arr2D) {
        row.sort()
    }
}

fun main() {
    val arr2D = arrayOf(
        intArrayOf(3, 1, 2, 0),
        intArrayOf(9, 5, 4, 8),
        intArrayOf(8, 7, 6, 2)
    )

    sortRows(arr2D)

    arr2D.forEach { println(it.joinToString(" ")) }
}

  
     
/*

0 1 2 3
4 5 8 9
2 6 7 8
