Question

The sport of amateur boxing requires opponents to be in the same weight category to compete. For this exercise, we will consider the following categories for weights of women and men:

Class Name	Weight in kg
Welterweight	61-64
Lightweight	58-60
Featherweight	55-57
Bantamweight	51-54

Write a Python program that prompts for the weights of boxing competitors. Weights for this competition are between 51 and 64 kg. Accept the weights of all competitors until a zero or a negative number is entered. When all entries have been entered, determine how many competitors are in each category. If there are zero competitors in a category, do not list it. If there is only one competitor in a category, add one to the next higher category if there is one. If there is a single welterweight, do not move this competitor from the category. If a competitor weight is below 51 or above 64, add them to one of two new categories: TooLow, TooHigh. Calculate and print the average weight of all competitors in the competition. Your output must be self-explanatory.

Include a flowchart with your program.

Use the following data to check your work: 51, 59, 62, 63, 49, 54, 53, 52, 55, 66, 55, 50, 57, 0
