ArrayList.Repeat(Object, Int32) Method is used to return an ArrayList whose elements are copies of the specified value. Or in other words, this method is used when you want to repeat a specified element in the ArrayList. This method is an O(n) operation, where n is the number of times item should be copied.
public static ArrayList Repeat (object item, int count);
item: It is an Object to copy multiple times in the new ArrayList. The value can be null.
count: It counts the number of times item should be copied.
Return Value: This method returns an ArrayList with a count number of elements, all of which are copies of the item.
Exception: If the value of count is less than zero then this method will give ArgumentOutOfRangeException.
Below given are some examples to understand the implementation in a better way:
GFG GFG GFG GFG GFG GFG The count of the item is : 6
System.ArgumentOutOfRangeException: Non-negative number required.
