I try to change my code. It produces RE(Signal 8) #include <stdio.h> #include <math.h> #include <stdlib.h> #define max 50000 long bil_prima[5133]; bool prime[max+1]; void prima() { int i,j,x=0; int limit = (int) sqrt(max)+1; for (i=1;i<=max;i++) prime[i] = i&1; prime[0] = prime[1] = false; prime[2] ...

At the first time, I make a function to generate all prime between 1-50000. I think if i remake my code like that, it will increase the process. In my real code it's written like this long bil_prima[10000]={ 2, 3, 5, 7, 11, 13, 17, 19,..., 49853, 49871, 49877, 49891, 49919, 49921, 49927, 49937, 4993...

I got CE with this code #include <stdio.h> #include <math.h> #include <stdlib.h> long bil_prima[10000]={prime number between 1-50000} int prime(long angka) { int prime; if(angka==1) prime = 0; if(angka==2) prime = 1; if(angka==3) prime = 1; else for(long j=2; j<=sqrt(angka);j++) { if(angka%j==0) {pr...

get accccccccccccccc
thx.
OMG, I wasted my time to convert a and b to binary number and XoR them. With my previous code, I got WA. But with only one line code, I got AC. Thank u very much.

Re: Why my program use so many memory?

Why my program use 440 :-? memory?(10696) #include <iostream> int main() { int n,k; std::cin>>n; while (n!=0) { if (n<=100) std::cout<<"f91("<<n<<") = "<<91<<std::endl; else std::cout<<"f91("<<n<<") = "<<n-10<<std::endl; std::cin>>n; } return 0; } Maybe that one will be better. My code only use 396...

it has been a week here in acm.uva.es, i havent solved a single one :cry: Please never give up. ^_^ For the first time, I felt frustrated because always got AC after several WA or CE. Keep going :D Oh, I forgot to answer the topic question. Beacuse I'm still beginner programmer, my record is 4/day.
