Wrong Answer nsteps

Getting wrong answer in NSTEPS
#include<bits/stdc++.h>
using namespace std;

class nsteps
{
private:
struct point
{
int x;
int y;
};
int n;
point* data;
vector I;
vector I_2;
public:
nsteps(int num)
{
n=num;
data=new point[n];
I.push_back(0);
I_2.push_back(0);
I_2.push_back(2);
}

void read()
{
for(int i=0;i<n;i++)
{
cin>>data[i].x>>data[i].y;
}
}

long long int q(long long int x)
{
if(x==0)
return 0;
else if(x%2==1)
return q(x-1)+1;
else
return q(x-1)+3;
}

long long int w(long long int x)
{
if(x==2)
return 2;
else if(x%2==1)
return w(x-1)+1;
else
return w(x-1)+3;
}

void print()
{
for(int i=0;i<n;i++)
{
if(data[i].x<=10000 && data[i].y<=10000)
{
if(data[i].y==data[i].x)
cout<<q(data[i].x)<<endl;
else if(data[i].y==(data[i].x)-2)
cout<<w(data[i].x)<<endl;
else
cout<<“No number”<<endl;
}
else
cout<<“No number”<<endl;
}
}

};

int main()
{
int num;
cin>>num;
nsteps s(num);
s.read();
s.print();
return 0;
}

cannot figure out whats wrong in this.Thanx in advance.

“No number”

I haven’t checked anything else.

in java

import java.util.Scanner;
class q2
{
public static void main (String[] args)
{
int n,x,y,t=0;

    Scanner in=new Scanner(System.in);
    n=in.nextInt();
    for(int i=0;i<n;i++)
    {
        x=in.nextInt();
        y=in.nextInt();
        int k=x-y;
        
        if(k==0||k==2)
        {
        	if(x%2==0)
        		t=(x*2)-k;
        	else 
        		t=(x*2)-k-1;
        		
        	System.out.println(t);
        	t=0;
        }
        else
        	System.out.println("No Number");
    }
}
