Given two numbers represented by two linked lists, write a function that returns the sum list. The sum list is linked list representation of the addition of two input numbers. It is not allowed to modify the lists. Also, not allowed to use explicit extra space (Hint: Use Recursion)....
Given an array of numbers, arrange them in a way that yields the largest value. For example, if the given numbers are {54, 546, 548, 60}, the arrangement 6054854654 gives the largest value. And if the given numbers are {1, 34, 3, 98, 9, 76, 45, 4}, then the arrangement 998764543431 gives the largest value....
Given a sorted array of positive integers, rearrange the array alternately i.e first element should be the maximum value, second minimum value, third-second max, fourth-second min and so on. Examples:...
Given an unsorted array of nonnegative integers, find a continuous subarray which adds to a given number. Examples :...
Given a sorted array of positive integers, rearrange the array alternately i.e first element should be the maximum value, second minimum value, third-second max, fourth-second min and so on. Examples:...
Given an array, print the Next Greater Element (NGE) for every element. The Next greater Element for an element x is the first greater element on the right side of x in the array. Elements for which no greater element exist, consider the next greater element as -1....
Given a string, the task is to reverse the order of the words in the given string....
Given a pointer to the head node of a linked list, the task is to reverse the linked list. We need to reverse the list by changing the links between nodes....
Given a Singly Linked List, the task is to find the middle of the linked list. If the number of nodes are even, then there would be two middle nodes, so return the second middle node....
Given a Roman numeral, the task is to find its corresponding decimal value....
Given two numbers as strings. The numbers may be very large (may not fit in long long int), the task is to find sum of these two numbers....
