WHY my solution is giving wa for DIGJUMP where ive tried all the test cases

general

please help i am fed up
please can you provide a test casee`

A way to answer this type of question yourself:

result\_type your\_solution(input\_data){
  ...
}
result\_type some\_AC\_solution(input\_data){
  ...
}
int main(){
  result\_type result1, result2;
  while(1){
    Generate random input data
    result1 = your_solution(random\_input);
    result2 = some\_AC\_solution(random\_input);
    if(result1 != result2){
       print the incongruent test case that was randomly generated
       break;
    }
  }
  // figure out what you did wrong
}

ive already done that its not working all the answers are matching still mine is a WA plz give a test case i can give you the ideone link if you want
