Java or C++ problem !?!?!?
Posted by Valiok 22 Jan 2015 05:03
Here is my java code :


import java.util.Scanner;
public class Example{
    public static void main(String []args){
        Scanner in = new Scanner(System.in);
        int number1,number2,number3;
        int [] array;
        int position=0;
        boolean check=false;
        int sth;
        number1=in.nextInt();
        number2=in.nextInt();
        number3=in.nextInt();
        array = new int[number2];
        for(int i=0;i<=number2-1;i++){
            sth=(int)Math.pow(i,number1);
            if((sth-number3)%number2==0){
                array[position]=i;
                position++;
                check=true;
            }else if(i==number2-1 && check==false){
                System.out.println(-1);
                System.exit(0);
            }

        }
        for(int p=0;p<position-1;p++){
            for(int j=p+1;j<position;j++){
                if(array[p]>array[j]){
                    int t=array[p];
                    array[p]=array[j];
                    array[j]=t;
                }
            }
        }
        for(int i=0;i<position;i++){
            System.out.print(array[i] + " ");
        }
        System.out.println();
    }
}

I get an error on test#3 .
And on my C++ solution i get an error on test#6.



#include<iostream>
#include<cmath>
using namespace std;
int main(void){
unsigned short int N,M,Y;
cin>>N>>M>>Y;
unsigned short int X[M];
unsigned short int position=0;
bool some_check=false;
int sth;
for(int i=0;i<=M-1;i++){
    sth=pow(i,N);
    if((sth-Y)%M==0){
        X[position]=i;
        position++;
        some_check=true;
    }
    else if(i==M-1 && some_check==false){
        cout<<-1<<endl;
        return 0;
    }
}
for(unsigned short int i=0;i<position-1;i++){
    for(unsigned short int j=i+1;j<position;j++){
        if(X[i]>X[j]){
            swap(X[i],X[j]);
        }
    }
}
for(unsigned short int i=0;i<position;i++){
    cout<<X[i]<<" ";
}
cout<<endl;
return 0;
}


Please,any ideas ???
