Given a matrix of coins, Alice and Bob have to collect maximum coins with certain conditions.
Alice starts from top left corner and Bob starts from top right corner
They can move to (i+1, j+1) or (i+1, j-1) or (i+1, j)
They have to collect all the coins that are present at a cell
If Alice has already collected coins of a cell, then Bob gets no coins if goes through that cell again
Q2. Arithmetic Subarrays Problem Statement

Count the number of arithmetic subarrays in an array.
An arithmetic subarray has 3 or more elements with the same difference between consecutive elements.
Loop through the array and check for all possible subarrays with 3 or more elements.
If the difference between consecutive elements is the same, increment the count.
Return the count for each test case.
