Invoke Operator in Kotlin Hindi

Here are some expressions using invoke operator with corresponding functions in Kotlin.

Expression	Translated to
`a()`	`a.invoke()`
`a(i)`	`a.invoke(i)`
`a(i1, i2, ..., in)`	`a.inkove(i1, i2, ..., in)`
`a[i] = b`	`a.set(i, b)`

 operator fun invoke(x:Int){
 println("You are in invoke function with value of x ="+x)

fun main(args: Array<String>) {
 var e:Example = Example()
 e(10)
 }
