Nth Node from End in LinkedList

Nth Node from End in LinkedList 1) Find length of linked list. 2) Traverse (length-position+1) element from begin. //nth Node from end public Node nodeFromEnd ( Node head , int position ){ Node temp = head ; int length = 1 ; while ( temp . next != null ) { length ++; temp = temp . next ; } System . out . println ( "length" + length ); temp = head ; int c = 1 ; while ( c !=( length - position + 1 )) { temp = temp . next ; c ++; } return temp ; }

Heap implementation in JAVA

In this tutorial we will see all the functionalities of heaps implemented through java language. package com . problems . heap ; public class HeapFunctions { //Function to generate maxheapify where root is max than childs public void maxHeapify ( int Arr [], int i , int N ) { int largest ; int left = 2 * i + 1 ; //left child int right = 2 * i + 2 ; //right child System . out . println ( "left" + " " + left ); System . out . println ( "right" + " " + right ); System . out . println ( "Max size" + " " + N ); if ( left < N && Arr [ left ] > Arr [ i ] ) { largest = left ; System . out . println ( "largest left" + largest ); } else { largest = i ; System . out . println ( "largest i" + largest ); } if ( rig
