Problem You work for a financial services company that handles transactions involving 32-bit signed integer amounts. Your goal is to enhance security by implementing an additional check: reverse the digits of a given transaction amount to create a new reference code. If reversing the digits results in a value outside the valid range of transaction amounts, which lies between -2,147,483,648 and 2,147,483,647, then return a code indicating the operation is invalid. Otherwise, return the reversed amount as the reference code. Assume the environment does not allow you to store 64-bit integers (signed or unsigned). ...

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. ...
