Problem You are working at an accounting firm and need to combine financial reports from two different departments, let’s say Marketing and Sales. These reports are provided to you in electronic format as linked lists of numbers. Each node in the linked list represents one digit of a larger number. The digits are arranged in reverse order because this is how they were stored in their original databases. Your task is to create a combined financial report by adding the numbers from both departmental reports. This requires you to traverse both linked lists, starting from the head (leftmost) node and moving towards the tail (rightmost). As you add the digits of each position, you also need to carry over any value resulting from the addition that is greater than 9 (i.e., tens place). This new carried-over value will become the next digit in the combined number. ...

Problem 1: Summation Of Weights You have a list of items in a warehouse and we need to find two items whose combined weight equals a specific target weight. For example, imagine you are managing an inventory of various products at a distribution center. Given a list of product weights [2kg, 3kg, 8kg, 6kg, 4kg] and a target weight of 9kg, your task is to find the indices of the two products whose combined weight equals the target. In this case, the output would be [1, 3] because the items at positions 1 and 3 (3kg and 6kg) add up to the target weight of 9kg. ...
