How to convert a specific row of a decimal matrix to a string in Kotlin

Answer 1

fun convertRowToString(matrix: Array<IntArray>, row: Int): String {
    val cols = matrix[row].size   
    
    return matrix[row].take(cols).joinToString(" ")
}

fun main() {
    val matrix = arrayOf(
        intArrayOf(4, 7, 9, 18, 29, 0),
        intArrayOf(1, 9, 18, 99, 4, 3),
        intArrayOf(9, 17, 89, 2, 7, 5),
        intArrayOf(19, 49, 6, 1, 9, 8),
        intArrayOf(29, 4, 7, 9, 18, 6)
    )

    val row = 2
    val str = convertRowToString(matrix, row)

    println(str)
}
