# last

```kotlin
public fun <T> List<T>.last(): T {
    if (isEmpty())
        throw NoSuchElementException("List is empty.")
    return this[lastIndex]
}


val list = listOf(1, 2, 3, 4, 5)
println(list.last())  // 5
println(listOf<Int>().last())  // Error
```



```kotlin
// 식을 만족하는 것중 마지막 값을 반환
public inline fun <T> List<T>.last(predicate: (T) -> Boolean): T {
    val iterator = this.listIterator(size)
    while (iterator.hasPrevious()) {
        val element = iterator.previous()
        if (predicate(element)) return element
    }
    throw NoSuchElementException("List contains no element matching the predicate.")
}


val list = listOf(1, 2, 3, 4, 5)
println(list.last{ it > 3 })  // 5
println(list.last{ it > 7 })  // Error
```
