Can anyone tell me the maximum value for n???????

Towhid

Among all pairs with minimum sum of values I always take the one with minimum first element. So my code passes your test case. It fails this test case: 7 2 4 6 6 7 9 9 Your greedy would choose 9,2,9 as the first team, and wouldn't be able to make a second team. But When there are 7 persons, I know ...

Well, thanks. A small modification and got AC. The interesting thing is when both side has more than 3 soldiers, then the optimal way is to send most possible of them. However, the statement of the problem should be clearer.........

Towhid

1. no it is not necessary to send 3 armies always. they are the best possible player so they both plays optimally.

Is it? But the problem statement says:

It

Towhid

You cannot use all your army in attack. Read When attacking, at least one army must remain on the origin territory, so a player with 3 armies can only use 2 of them to attack an adjacent territory. The defense, however, can use all the available number of armies to defend, up to a maximum allowed nu...

Still problem here. Try

Code: Select all

1 6 8 10 25

This is not an A sequence, but your program outputs the opposite...

I think this doesn't work correctly. Try the input:

Code: Select all

5 1 6 8 10 12

This is an A-sequence, but what your program says?????

What is best? Is it the number of elements in the largest set? But you also have to count the number of possible sets. How can you cut off?

Towhid

The first thing is you should not sort the data. And 2nd thing when there is a thread containing the same problem use that thread, don't create a new one. However you haven't checked if the data are strictly increasing order. Try it...

I think now I understand the problem. I had some wrong idea. But now I have same kind of problem. My code outputs 172 for 100. for 171 the probability is 0.4986... Most of the outputs matches. I have used: p(m,n)=p1*p(m,n-3)+p2*(m-1,n-2)+p3*(m-2,n-1)+p4*(m-3,n) where p1=6420.0/46656.0; p2=10017.0/46...

Hi kodder I have found your problem.Your code fails to give the correct output to the following input. Input: 4 0 6 0 Your program terminates here while the correct output is: Sums of 4: NONE Sums of 6: NONE I don't think that is the case. Because when n==0 the program should terminate: If n = 0 it...

well... in my process i had written PRIME() function which returns 0/1 according to whether it is prime or not when i need to check primality for a number > sqrt(10^9) but no one here mentioned for such process. so am i doing inefficient some where? You can use 3*10^7 size char array for flagging, ...

Towhid

Well........ I have found my mistake. A silly one. Got Ac in 6.6 secs.......

I have used Greedy approach. The code is a bit big with some if else condition. I started from the first entry....
