      let p = String.fromCharCode(90);
      let q = String.fromCharCode(97);
      let r = String.fromCharCode(98);
      let s = String.fromCharCode(121);
      let t = String.fromCharCode(122);

      document.getElementById("a").innerHTML = m;
      document.getElementById("b").innerHTML = n;
      document.getElementById("c").innerHTML = o;
      document.getElementById("d").innerHTML = p;
      document.getElementById("e").innerHTML = q;
