interface MutableIterator<out T> : Iterator<T>

An iterator over a mutable collection. Provides the ability to remove elements while iterating.

MutableCollection.iterator

abstract fun remove()

Removes from the underlying collection the last element returned by this iterator.

abstract operator fun hasNext(): Boolean

Returns true if the iteration has more elements.

abstract operator fun next(): T

Returns the next element in the iteration.

asSequence	fun <T> Iterator<T>.asSequence(): Sequence<T> Creates a sequence that returns all elements from this iterator. The sequence is constrained to be iterated only once.
forEach	fun <T> Iterator<T>.forEach(operation: (T) -> Unit) Performs the given operation on each element of this Iterator.
iterator	operator fun <T> Iterator<T>.iterator(): Iterator<T> Returns the given iterator itself. This allows to use an instance of iterator in a `for` loop.
withIndex	fun <T> Iterator<T>.withIndex(): Iterator<IndexedValue<T>> Returns an Iterator wrapping each value produced by this Iterator with the IndexedValue, containing value and it's index.

interface MutableListIterator<T> : 
    ListIterator<T>, 
    MutableIterator<T>

An iterator over a mutable collection that supports indexed access. Provides the ability to add, modify and remove elements while iterating.
