In this program, You will learn how to find duplicate elements in the array in Kotlin.
List is: 2 3 4 5 2 3 4 5 9 10
Duplicate elements is: 2 3 4 5
import java.util.Scanner
fun main(args: Array<String>) {
var v = 1
val arr = IntArray(5)
val sc = Scanner(System.`in`)
print("Enter 5 elements:")
for (i in 0 until arr.size) {
arr[i] = sc.nextInt()
}
print("Duplicate element list are:")
for (i in 0 until arr.size) {
for (j in i + 1 until arr.size) {
if (arr[i] == arr[j]) {
if (v == 1 && arr[j] != 0) {
print("${arr[i]} ")
}
arr[j] = 0
v++
}
}
v = 1
}
}
Enter 5 elements:10 20 10 20 30
Duplicate element list are:10 20
