The repository contains two files: ZapposApi and ZapposBackEnd The ZapposApi.py is the function that is to be executed. It mainly accesses the api and searches for products whose value is lesser than the cost mentioned by the user. It uses the price facet provided by the Zappos api. Once, products have been extracted, they are passed on to the callFinder function of ZapposBackEnd.py. This inturn makes call to the finderList function which is a recursive function implementing the subset-sum method for two criteria: cost target and number of products. The list computed is returned back to the callFinder which sorts the list based on the total cost value of products selected and returns the new sorted list. The ZapposApi function then displays this list, 10 at a time. Here, limit value is set to 100.
