1. (100 points) Assume daily income and expenses are given for each person as follows: \[ \begin{array}{l} \text { Income }=\{\text { 'ali':100, 'amy': } 1000, \text { 'ayse': } 600\} \\ \text { Expense }=\{\text { 'ali':50, 'amy':700, 'ayse': } 800\} \end{array} \]

Write a Python function that finds the people whose net balance is positive (Net balance = Income - Expense) and returns their names and net balance as a list of tuples.

For example, for the dictionaries given above, the function should return: [('ali', 50), ('amy', 300)] Your code SHOULD work for any given input dictionaries.
