Code Question 1
In order to ensure maximum security, the developers at Amazon employ multiple encryption methods to keep user data protected.
In one method, numbers are encrypted using a scheme called 'Pascal Triangle'. When an array of digits is fed to this system, it sums the adjacent digits. It then takes the rightmost digit (least significant digit) of each addition for the next step. Thus, the number of digits in each step is reduced by 1. This procedure is repeated until there are only 2 digits left, and this sequence of 2 digits forms the encrypted number.
Given the initial sequence of the digits of numbers, find the encrypted number. You should report a string of digits representing the encrypted number.
Code Question 2
Imagine you're a seller on Amazon, specializing in eco-friendly home products. Each of your items is rated by customers based on its quality and environmental impact.
The overall qualityScore of your products is determined by the maximum possible sum of consecutive ratings.
To improve the qualityScore of your products and attract more customers, you are given an integer impactFactor and the following two strategies:
- Amplify Ratings: Select a contiguous segment of ratings and amplify them by multiplying each rating in that range by impactFactor.
- Adjust Ratings: Select a contiguous segment of ratings and adjust them by dividing each rating in that range by impactFactor.
Your task is to determine the maximum possible qualityScore for your eco-friendly products after applying exactly one of these strategies.
Note: When applying the second strategy, i.e., Adjust Ratings:
For dividing positive ratings, use the floor value of the division result, and for dividing negative ratings, use the ceiling value of the division result.
