Alex is shopping at Ozone Galleria Mall. There is a dedicated cubicle for a type of product at the shopping center. All the products sold at the ith cubicle are priced the same, denoted by prices[i]. The cubicles are arranged such that the price of the products sold at each cubicle are in non- decreasing order. Several queries would be asked in the problem. In each query, the cubicle number Alex is initially standing at, and the amount of money Alex has is given, and Alex can travel in the right direction visiting from the current cubicle to the last cubicle. Alex may buy at most one item from any cubicle visited, but the total cost of the purchase must not exceed the amount Alex has. Report the maximum number of products that can be purchased for each query. More formally, given an array of n integers, prices, where prices[i] denotes the price of the product sold in the th cubicle. The array prices are in non-decreasing order (i.e., price[i] s price[i+1]), and q queries need to be processed. For each query, two integers are given: • pos: Alex's initial position amount: the amount of money Alex has Alex needs to visit each cubicle from number pos to n, purchasing at most one product from each cubicle. For each query, the goal is to find the maximum number of products that Alex can buy. Alex is shopping at Ozone Galleria Mall.
