How to pad an array to a specified length with a given value in Kotlin

Answer 1

fun arrayPad(arr: IntArray, size: Int, value: Int): IntArray {
    val originalSize = arr.size
    if (size < originalSize) {
        return arr;
    }
    val paddedArray = IntArray(size)

    // Copy original array elements
    for (i in arr.indices) {
        paddedArray[i] = arr[i]
    }

    // Pad the array with the given value
    for (i in originalSize until size) {
        paddedArray[i] = value
    }

    return paddedArray
}

fun main() {
    val arr = intArrayOf(1, 2, 3, 4)
    val size = 7
    val value = 0

    val paddedArray = arrayPad(arr, size, value)

    for (num in paddedArray) {
        print("$num ")
    }
}
