Returning a new array created from adding odd numbers from an array
I am trying to create an array from this following array arr=[1,2,3,4,5,6,7,8,9] and it will return as sum of numbers in this way 1+3 =4 ,3+5=8,5+7=12,7+9=16. so that final answer would be newArray =[4,8,12,16].
How can I achieve it. I have done below code but it doesn't work .
fun main(){

val sum = arrayOf(1,2,3,4,5,6,7,8,9)
var first =0;
var second=0

for (i in sum.indices){
if(sum[i]%2!=0){
first += sum[i]
if (second!=0){...
