SUPyF Exam 24.03.2019 - 01.Build a Building

Problem:
We are going to try to build a building. For that we will receive the budget, of course we have initial capital –
m  and after that we will receive n – the number of investors who are interested to take place in our project.
In the next n-lines we will receive numbers (one at a row) – the money which investors want to give us.
For every investor we must print information in the following format:

‘Investor {number} gave us {money_given}.’
Where {money_given} is formatted two digits after the decimal point.

If at some point we have enough money to build our building we should stop taking investors money and print:

‘We will manage to build it. Start now! Extra money - {extra_money}.”


If we didn’t collect enough capital after all investors’ money we must print:

‘Project can not start. We need {money} more.’

Input
You will recieve on the first 3 lines:
• budget – the budget we need to build the building [floating  number]
• m – the initial capital we have[floating number]
• n – number of investors [integer number]
For each investor you will receive:
• money – The money that this investor has given to us [floating  number]

Output
If you have enough money at some point
• „We will manage to build it. Start now! Extra money - {extra_money}.”
Where extra_money is the money which has left, formatted two digits after decimal point
If you do not have enough money after all investors have invested print:
• „Project can not start. We need {difference} more.”
Where {money} is the money you need to reach the planned budget, formatted two digits after decimal point.

Example input/output:
    Input:
        2250000
        675000
        3
        1000000
        750000
        450000
    Output:
        Investor 1 gave us 1000000.00.
        Investor 2 gave us 750000.00.
        We will manage to build it. Start now! Extra money - 175000.00.
    Input:
        15000000
        300000.99
        2
        2000000.37
        8000000.25
    Output:
        Investor 1 gave us 2000000.37.
        Investor 2 gave us 8000000.25.
        Project can not start. We need 4699998.39 more.
