Yeah i've removed the = 0 and it's the same time 👌🏿 thanks
Ralph
Is there anything else i can do for it?
Igor🇺🇦
I have a function above for divide and conquer, and that function i sent is for the exhaustive result
That does not explain what are you doing in the function. What does it mean brute sum? What are you calculating?
Ralph
I am trying to get the maximum sub array sum in 2 tries. The first is divide and conquer, and the second (which i sent) is a brute calculation for it

Is this the problem you're trying to solve https://en.wikipedia.org/wiki/Maximum_subarray_problem?

Yes but i guess here they are doing it by divide and conquer. I've written the code for the brute but it is taking a hell of time

There exists algorithm that makes it in O(N). In your case only this step is O(N^2).
Ralph
So it should be like that?
Ralph
Or is there a way to make it in O(N)
Ralph
I will check it
Ralph
Thank youu

Can any one allow me to send the problem by video ?

HI , Is there any alternatives for <sys/time.h> in windows?
Manish
or something else which works on cross platform?

Hello. How can i implement a function that returns the maximum possible profit but using divide and conquer.
I have to use templates so the parameters should be Iter start and Iter end only
Vlad
Nooo, no ctime while there's chrono
He didn't specified his programming language. Maybe he's got C

Hello, how to create a calculator that can use any arithmetic operator in the same time? For example, calculate 2+6-1*8/9

Because, what I find in Google is only show all those simple calculator. I knew that

Using C
Data structures and Algorithms
Stack - Operator precedence, Infix, postfix
Learn it.

You can use that to create a calculator in C

Hmm Bro, only use switch and case can create mix operator calculator?

If you want it to process operations in the correct mathematical order you probably need something like abstract syntax tree

Hi, Is there anything equivalent to release() for a raw pointer?

Does anyone know why how to fix the error "Non-Void function does not return a value in all control path"

Every branch of your if-operators should contain return.
Ralph
It contains
Ralph
That's what is disturbing
Артём
Every branch of your if-operators should contain return.
I mean, there should not be any path to exit function without return .
Vlad

auto foo()
{
...
return {};
}
Ralph
I still have the error
Ralph
If i add a return after my if { return expression;} it works
Ralph
But i have 3 if's with each a return and i have the error at the closing bracket of the function
Ralph
I will send 2sec

int peak(std::vector<int>& v, int start, int end) {
int middle = (start + end) / 2;
if ((v[middle] >= v[middle - 1]) && (v[middle] >= v[middle + 1])) {
return middle;
}
if (v[middle] < v[middle - 1]) {
return peak(v, start, middle - 1);
}
if (v[middle] < v[middle + 1]) {
return peak(v, middle + 1, end);
}
}
Ralph
And how should i call it
Ralph
I mean i want the return if the expression is true
Vlad
Or else it might fall through
Артём
int peak(std::vector<int>& v, int start, int end) {
int middle = (start + end) / 2;
if ((v[middle] >= v[middle - 1]) && (v[middle] >= v[middle + 1])) {
return middle;
}
if (v[middle] < v[middle - 1]) {
return peak(v, start, middle - 1);
}
if (v[middle] < v[middle + 1]) {
return peak(v, middle + 1, end);
}
}
the way no one of these if's gets satisfied is still there.
Ralph
What do you mean
Ralph
Oh
Vlad
It simply assumes that they wont
Ralph
Yeah i see. That's why when i return a value outside of the if's it works?
Vlad
Vlad
Didn't get anything
Ralph
I've added a return 1; after all the if functions. The build succeeded, and it returned 1
Vlad
Vlad
You could return smth like -1
Ralph
Yeah and it worked
Vlad
To indicate out of bounds or smth
Ralph
Yeah i see
