list of some important Data Structures and Algorithms (DSA) questions related to arrays:Array reversal: Reverse an array in-place.Array rotation: Rotate an array to the left or right by a given number of steps.Maximum subarray sum: Find the contiguous subarray within an array that has the largest sum.Find duplicates: Find duplicates in an array with O(n) time complexity and O(1) extra space.Merge two sorted arrays: Merge two sorted arrays into a single sorted array.Find missing number: Find the missing number in an array of integers from 1 to n.Array partitioning: Partition an array into two subsets such that the difference of their sums is minimized.Find majority element: Find the majority element in an array (element appears more than n/2 times).Move zeros: Move all zeros to the end of an array while maintaining the relative order of the non-zero elements.Stock Buy and Sell: Given an array representing stock prices on different days, find the maximum profit that can be earned by performing at most one transaction (buying and selling one share of the stock)
