Question

Write a method that could be added to a LinkedintList class. The method accepts an integer k as a parameter and removes all values in the list less than this value, not including the value itself. Suppose a LinkedlntList variable list stores the following values: [21,8,15,8,32] The call should change the list to store the following values: Assume that we are adding this method to the class as shown below. public class Linkedintlist } private Listliode front; II ...constructors and other methods not shown... I/ YOUR CODE IS ADOED HERE 3 pub1ic class Listnode \{ pub1ic int data; public ListNode next; II ... constructors not shown... ) You may not call any other methods of the class to solve this problem, and you may not use any auxiliary data structures to solve this problem (such as an array, ArrayList Queue, String, etc.). You may create a single ListNode temporary pointer to aid in solving the problem.

Answer 1

To remove values less than a given number from a LinkedList, iterate through the list and update the 'next' pointers of the previous nodes.

Step-by-step explanation:

To solve this problem, we can iterate through the linked list and check each node's value. If the value is less than k, we can remove that node from the list. This can be done by updating the 'next' pointer of the previous node to point to the next node after the current one.

Here is the Java code for the method:

public void removeLessThan(int k) {
ListNode current = front;
ListNode prev = null;
while (current != null) {
if (current.data < k) {
if (prev == null) {
front = current.next;
} else {
prev.next = current.next;
}
} else {
prev = current;
}
current = current.next;
}
}
