This day is marked by various mathematical challenges and games that put the villagers' arithmetic skills to the test. This year, the villagers are embarking on a quest to explore the distinctive properties of subarrays within integer arrays. The village's renowned mathematician, Professor Arithmo, has crafted an intriguing challenge. He has provided the villagers with an integer array nums`and two additional integers, K and P. Professor Arithmo's challenge revolves around discovering and counting distinct subarrays from the array nums. The uniqueness of these subarrays is determined by their divisibility characteristics.

 Alex and his Array code TechGig Geek Goddess 2023: 100% Working Code uploaded on Youtube: https://youtu.be/6cn7nNtSiKo 100% Working Code uploaded on Telegram: https://telegram.me/PLACEMENTLELO Alex and his array (100 Marks) Meet Alex, a bright student who is dealing with an array challenge today. He has been given an array a1, a2, ..., aN of length N. The intriguing aspect of this challenge is that Alex can perform various operations on the array elements. In a single operation, Alex is allowed to choose two indices l and r, where 1 ≤ l ≤ r ≤ n. He can then multiply all the elements in the subarray [al, al+1, ..., ar] by -1, effectively reversing their signs. Being pressed for time as he is running late for school, Alex is seeking your assistance in determining the maximum possible sum of numbers in the array. Additionally, he is eager to find out the minimum number of operations required to achieve this maximum sum. Input Format The first line contains an integer N, the length of the
