Senior Software Engineer

You are given two Singly Linked Lists of integers, which may have an intersection point.

Your task is to return the first intersection node. If there is no intersection, return NULL.

Example:-

The Linked Lists, where a1, a2, c1, c2, c3 is the first linked list and b1, b2, b3, c1, c2, c3 is the second linked list, merging at node c1.

Given an array/list ‘ARR’ of integers and an integer ‘K’. You are supposed to return the maximum for every subarray of the given array of length ‘K’.

Note :

An array ‘B’ is a subarray of an array ‘A’ if ‘B’ that can be obtained by deletion of, several elements(possibly none) from the start of ‘A’ and several elements(possibly none) from the end of ‘A’. 

You are given an array 'ARR' of distinct positive integers. You need to find all numbers that are in the range of the elements of the array, but not in the array. The missing elements should be printed in sorted order.

Example:

If the given array is [4, 2, 9] then you should print "3 5 6 7 8". As all these elements lie in the range but not present in the array.
