Generate a vector like 1,2,2,3,3,3,4,4,4,4
So if n = 3, then return
[1 2 2 3 3 3]
And if n = 5, then return
[1 2 2 3 3 3 4 4 4 4 5 5 5 5 5]
function ans = GenerateVector(n)
ans = 1;
for n = 2:n
ans = [ans n*ones(1, n)];
end
could sb explain me why this code is flagged a as a bad one ?? it works !! and another thign in problem definition it is not clearly stated that the solutions must be straight code without writing a function. I wrote a function and it works well to the definition of the problem. then I am getting incorrect information after submission. dear cody team: please write more specific requirements of the problem. you will miss many misunderstandings then.
Your function has to use exactly the same name that is provided in the function template. In this case, the function must be called "you_fcn_name". You wrote a function called "GenerateVector". Change the name of your function and it should pass.
The test suite has been expanded.
Good problem.
Is there any way to avoid the for loop? I really want to but I don't see how right now.
Good one! took some time but finally did it.
Can it be done without a for loop?
Good problem.
HINT:
use command "repelem"
Solution:
A=1:n
B=repelem(A,1:n)
great problem. Interesting for beginners like me.
can we do it without loops?
good
good problem
ans=0
for i=1:n
for j=1:i
ans(end+1)=i;
end
end
ans(:,1)=[] %delete first column
The suggestion leads to wrong answers because of "ans".
It would be nice to know how the leading solution was do to be so small.
My solution size is at least 6 times than the leading solution. I would like to be enlightened...
what's wrong with my answer? it gives exactly the right answer just not in []
also the test suite says it gives you x but when you use x in the function it doesn't recognize x you have to use n
Great problem
Funny, I just tested you SO post too, and it has 2 nodes lest without the assignment to ans. I don't get this yet...
neat and elegant.
didn't even known about Henkel's matrix
could sb please explain me politely why this code has been rated as an incorrect one ? if you paste this in m-file it works !!!
Function name should be your_fcn_name
good
