Problem 2: Top Alternative Selections Thank you for your greatjob helping Marlon with the warehouse storage arrangement! In this part, he would like to simulate the situation when a random warehouse is out-of-stock during the promotion period. It is common that a warehouse would run out of all the products during promotion, and in order to keep the promotion activities and make sure on-time delivery in one region, cross-region shipment from other warehouses [let's call them "Helpers") is necessary. More specifically, among the 300 warehouses, 1 is out-of-stock, then the rest 299 would all be Helpers. Before seeking help from those Helpers, Marlon needs to figure out which Helpers he could choose. For Helpers selection, Marlon would choose those Helpers with the top 10 highest "Va|ue_per_Weight" ratios. It's acceptable to recommend more than 10 Helpers because two or more Helpers may have the same "Value_per_Weight" ratio
