Is there any other efficient manner of checking duplicate characters from string2 in string1

     char st1[6]="mikem";
      char st2[5]="Tame";
      int l1=strlen(st1);
      int l2=strlen(st2);
      int i,j;
      
     for( i=0;i<strlen(st2);i++)
     {
           
            for( j=0;j<l1;j++)
            {   if(st1[j]=='\0')
                continue;
                   
                if(st2[i]==st1[j])
                {    
                    st1[j]='\0';
                }
            }
       }

The above is checking each and every alphabet from st2 and replacing it with null in st1 ,if match is found

Is ther Any other more efficient way , rather than this one

-thank you
