All kinds of test cases are giving the right output but when i submit it , it always shows “wrong answer”

can anyone tell me whats wrong??

#include <algorithm>
#include <iostream>
#include <cstdio>
using namespace std;

#define gc getchar_unlocked

void scanint(int &x)

{
    register int c=gc();
    x=0;
    for(;(c<48||c>57);
    c=gc());
    for(;c>47&&c<58;c=gc()) 
    {
    	x=(x<<1)+(x<<3)+c- 48;
    }
}

int main() 

{
	int t,n,m,sum,j,i;

     int notes[20];
	 scanint(t);
	 while(t--)
	{
		scanint(n);
		scanint(m);
		
		for(i=0;i<n;i++)
		{
			scanint(notes[i]);
			
		}
		sort(notes,notes+n);
		
		for(i=0;i<n;i++)
		{   sum=notes[i];
			for(j=0;j<n;j++)
			{
				if(sum<m)
			   {
			     sum=sum+notes[j];
			     if(sum>m)
			     sum=sum-notes[j];
			   }
			}
			
			for(j=0;j<i;j++)
			{
				if(sum<m)
				sum=sum+notes[j];
				if(sum>m)
			     sum=sum-notes[j];
				
			}
			if (sum==m)
			break;
		}
		if(sum==m)
		printf("Yes\n");
		else
		printf("No\n");
	}
	return 0;
}

i rectified the code, its yet showing wrong answer

#include
#include
using namespace std;

#define gc getchar_unlocked

void scanint(int &x)

{
register int c=gc();
x=0;
for(;(c<48||c>57);
c=gc());
for(;c>47&&c<58;c=gc())
{
x=(x<<1)+(x<<3)+c- 48;
}
}

int main()

{
int t,n,m,sum,j,i;

 int notes[20];
 scanint(t);
 while(t--)
{
    scanint(n);
    scanint(m);

    for(i=0;i<n;i++)
    {
        scanint(notes[i]);

    }
    

    for(i=0;i<n;i++)
    {   sum=notes[i];
        for(j=i+1;j<n;j++)
        {
            if(sum<m)
           {
             sum=sum+notes[j]; 
             if(sum>m)
             sum=sum-notes[j];
           }
        }

        for(j=0;j<i;j++)
        {
            if(sum<m)
            {sum=sum+notes[j];
            if(sum>m)
             sum=sum-notes[j];
            }

        }
        if (sum==m)
        break;
    }
    if(sum==m)
    printf("Yes\n");
    else
    printf("No\n");
}
return 0;

}
