Question

can someone explain how can i do this program pls using c++

Answer 1

The bank would obviously like to make the most
favourable such statement it can (i.e., find the period for
which the average daily profit is the highest). However,
it will only consider periods of at least a M days, since
the customers will be suspicious if they indicate the profit
over too short a period to be meaningful.
Example
Suppose that the bank made the following amounts for
the customer over a number of days: R15, −R10, R10,
R11, R10, R2, R10, R9, R11, R1; and that it wants to tell
the customers about a period of at least 4 days. Then it
can announce that from the 3rd to the 9th day (inclusive),
it made an average of R9 a day.
Input
The first line of input contains an integer T, the number
of test cases. T test cases follow.
The first line of each test case contains two integers,
N and M, separated by a space. The next N lines each
contain an integer Pi, the profit (or loss, if negative) that
the bank made on day i. Days are numbered from 1 to
N.

@dpaInc pls help

Answer 3

@agent0smith hepl!

Answer 4

Sorry man, I don't think I've ever used C++

Answer 5

Where exactly are you stuck? Can you already read in the input data?

Answer 6

i understand it ,but the coding part i don't know how can i doit

Answer 8

The best way is to subdivide the code into parts and work on it one step at a time. In your program you're going to need to:
1) Read the input data and store it in an array/vector
2) Loop through the array and find the largest consecutive sum
3) Display the results

Now the big question: how to write code for those parts? The best way IMHO is by reading some online tutorials or a good book on C++ programming.
