How to find middle element of linked list in java

First, we will find the total size of the linked list. Then, we divide the total size by 2, and then whatever number comes, we move the pointer, starting from the head node, to that number of times. The node at which the pointer is pointing is the middle node of the linked list.

How to find mid element in Java?

int mid = firstIndex + (lastIndex-firstIndex)/2 , will give you the mid of the array.

LinkedList get() Method in Java

util. LinkedList. get() method is used to fetch or retrieve an element at a specific index from a LinkedList. Parameters: The parameter index is of integer data type that specifies the position or index of the element to be fetched from the LinkedList.

How do you find the middle element of a linked list in a single iteration?

In each iteration, the ptr1 will access the two nodes and the ptr2 will access the single node of the linked list. Now, when the ptr1 reaches the end of the linked list, the ptr2 will be in the middle. In this way, we are able to get the middle of linked list in a single iteration.

How do you find the middle element of a linked list without traversal?

To find the middle element of a linked list, there are two possible approaches: Iterate the list of elements once and count the number of nodes in the list. Once again iterate through the list this time only till the (count/2) position. The element at position (count/2) is the middle element.

How do you find the middle of a value?

The median is the middle value in a set of data. First, organize and order the data from smallest to largest. To find the midpoint value, divide the number of observations by two. If there are an odd number of observations, round that number up, and the value in that position is the median.

How do you find the mid element of an array?

Given an integer array of size n and a number k. If the indexing is 1 based then the middle element of the array is the element at index (n + 1) / 2, if n is odd otherwise n / 2.

What does find () do in Java?

Java Matcher find() method

The find method searches the specified pattern or the expression in the given subsequence characterwise and returns true otherwise it returns false.

How do I search for a position in LinkedList?

LinkedList indexOf() method in Java

LinkedList. indexOf(Object element) method is used to check and find the occurrence of a particular element in the list. If the element is present then the index of the first occurrence of the element is returned otherwise -1 is returned if the list does not contain the element.

How to find the middle element of a linked list in C?

Traverse linked list using two pointers. Move one pointer by one and the other pointers by two. When the fast pointer reaches the end slow pointer will reach the middle of the linked list.

What is the middle node of linked list?

First, we will find the total size of the linked list. Then, we divide the total size by 2, and then whatever number comes, we move the pointer, starting from the head node, to that number of times. The node at which the pointer is pointing is the middle node of the linked list.

How to find middle of linked list in javascript?

Traverse the linked list using 2 pointers i.e. slow and fast pointer. Move the slow pointer one node at a time and the fast pointer two nodes at once until the fast pointer points to null. When the fast pointer reaches the end slow pointer will point to the middle element.

How do you find the middle element of a linked list in Python?

Method 2: Traverse linked list using two pointers. Move one pointer by one and another pointer by two. When the fast pointer reaches the end slow pointer will reach middle of the linked list.

How to find middle element in ArrayList Java?

size() / arraylist. length() method; you can use two iterators. One of them iterates from beginning to the end of the array, the other iterates from end to the beginning. When they reach the same index on the arraylist, then you find the middle element.

How do you find the middle Most element in an array?

Given an integer array of size n and a number k. If the indexing is 1 based then the middle element of the array is the element at index (n + 1) / 2, if n is odd otherwise n / 2.
