You work for a shipping company and your manager receives orders from various customers every day (some existing, some new). your manager wishes to establish a process to automate tracking the orders received by the company. you can assume the daily data arrives as a list/array/vector of strings and follows this exact format (note that customers may place separate orders in a single day): day_i = ["bob: 100", "alice: 100", "celia: 110", "bob: 20",

write a script that, when given the daily data, will keep track of the total purchase amount for each customer. you can assume that the data "day_i" already exists in memory (i. e. you don’t need to read it from a text file or database). your output should ideally look like: customer total purchase alice 100 bob 120 celia 110
