Write a function to get the statistics of quarter sales. This function accepts a list, by iterating this

list, this function can return a dictionary. For example, the sales are 100, 50, 70, 105, 90, 59, 78, 200,

130, 180, 60, 105 million from January to December respectively, so by passing the list of [100, 50,

70, 105, 90, 59, 78, 200, 130, 180, 60, 105] to this function, we can get a dictionary of ("First

quarter": 220, 'Second quarter: 254, 'Third quarter: 408, 'Fourth quarter": 345). Then based on this

dictionary to draw a bar chart to visualize them using Matplotlib. After drawing such chart, please
