Dsa question

Problem Statement

You are given N trees and K units of total water. Each tree initially requires M units of water. For the ith tree:

• array1[i] denotes the number of additional times the tree needs to be watered.
• array2[i] denotes the amount of water required during each additional watering. The total water required by the ith tree is: M + (array1[i] × array2[i]) Calculate and return the amount of water remaining after watering all N trees. If the total water required is greater than K, return 0. Input:
• An integer N, representing the number of trees.
• An integer K, representing the total available water.
• An integer M, representing the initial water requirement of each tree.
• An array array1 of size N.
• An array array2 of size N. Output: Return the remaining amount of water: max(0, K - totalWaterRequired)
