function CompareFunction(string1, string2) {
    if (string1.length == string2.length) {
        return parseInt(string2) - parseInt(string1);
    }
    else {
            return string2.length - string1.length;
        }
}
  
 
const arr = ["7", "0", "55", "8", "9", "6"];
  
arr.sort(CompareFunction);
  
for (let i = 0; i < arr.length; i++) {
    console.log(arr[i]);
