Challenge 3: Deletion by Value

Problem statement

Implement the Delete functionality. In this function, you will pass a particular value that you want to delete from the list. The node containing this value could be anywhere on the list. It is also possible that such a node may not exist at all.

Therefore, you would have to traverse the whole list until you find the value, which needs to be deleted. If the value does not exist, you do not need to do anything.

Input

A value to be deleted is the input.

Output

true if the value is deleted but false otherwise.

Sample input

LinkedList = 1->2->3->4->5
Value = 4

Sample output

true
