@taran_1407 but wouldn’t the calculator print exactly 09 only?
Which language you are talking about mate??
I work with java. Either share code link. 
Nope, It isn’t mentioned in problem but a calculator always print 9, not 09. You may try.
Yes, but since the calculator is faulty and skips carry i thought it should print 5555+5555 as 0000.
Thanks for replying though.
No problem at all.
By the way, the calculator isn’t that faulty

The logic of your code isn’t clear to me. Can you elaborate??
Agreed
That ought to be the case, but i thought of real life calculators, which never print 0000. Maybe the author’s calculator wasn’t that faulty to print 0000.

Mate, in his solution, that matters not.
Because he used the condition a>0 || b > 0
If one of them is zero, it will be automatically ignored.
for each i erased character at that place…
And checked the string so formed is divisble by 6 or not
check condition in O(1)
condition:
1.check even or not
2.if yes check (sum-a[i])%3 or not
I think it’s just because erase giving Tle
Possible XD. Imagine my reaction when I opened comment section after 20min only to realzie that leading zeroes are giving WA. I was like, “… (xinfinity)XDXD”

Your code can only delete 3,6 and 9 from given number due to line
if(p%3==0)
Further, no need to check sum%3==0
Simply check (sum-d)%3==0 where d is the deleted digit.
As far as i know about c++, String s = p itself takes Linear time, making your solution time out.
How Come??
Surely you can ask anything here mate…
Happens Mate…
I see you haven’t participated in lunchtime…
Ask away mate…
I did use two loops but not two nested loops. There’s a difference. Nested loop is loop within a loop, which i haven’t used and you have.
That’s what that make the difference.
@taran_1407 the very first solution that passed is O(N^2)! Can you please look at his code and please comment that whether the test cases are weak or he has made some optimization ?
