help with for loop

i running code receive rfid data, not whole code, when run code gives me output (below code).
where finds code writes there(if code placed 1st in array displays there).
how can receive "authorize" "not authorize" when finds whether in array or not

boolean asd;
for(int l=0;l<5;l++)
{
        for(int o=0;o<5;o++)
            {

 
  if(tagin

• ==data[l]
• )
    {
      asd=true;
     
    }
    else
    {
      asd=false;
     }
  
              }
  
   
    switch(asd)
    {
    case true:
    {
        for(int k=0;k<5;k++)
    serial.print(tagin[k]);
    serial.println("\nauthorize");
    break;
   
    }
   
    case false:
    {
    serial.print("\nnot authorize\n");
    break;
      }
   
    }
  }
