output should be YES, but in testcase it is mentioned as NO

My code

/* package codechef; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Codechef
{
	public static void main (String[] args) throws java.lang.Exception
	{
		// your code goes here
		Scanner sc=new Scanner(System.in);
		int t=sc.nextInt();
		while(t-->0)
		{
		    int n=sc.nextInt();
		    int x=sc.nextInt();
		    int y=sc.nextInt();
		    String s=sc.next();
		    int xi=0,yi=0;
		    int remainingMoves=0,manhattanDistance=0;
		    for(int i=0;i<s.length();i++)
		    {
		        char ch=s.charAt(i);
		        if(ch=='R')
		        xi++;
		        else if(ch=='D')
		        yi--;
		        else if(ch=='L')
		        xi--;
		        else if(ch=='U')
		        yi++;
		        
		         
		    }
		    if (x-xi <=n || y-yi<=n)
    		      System.out.println("YES");
    		else
		      System.out.println("NO");
		}
	}
