There are a few bugs , some cases you missed
Bug 1 :
When you did this :
if(ans == 1)
{
for(int i=0;i<n;i++)
{
if(a[i]%3 == ans)
{
pos = i;
break;
}
}
// cout << ans << " " << a[pos] << endl;
for(int i=n-1;i>=0;i–)
{
if(pos!=i)
cout << a[i] ;
}
}
You’ve done for the case if there were some digits such that digit %3 == 1
But what happens if there isn’t.
Try to think how to solve then ( Hint : You managed to do that for ans==2 )
This bug fails the code for tests like :
5
3 2 2 0 0
actual output : 300
your o/p : 32200
Bug 2 :
Even if you find a digit such that digit%3==1 , you should check are all the remaining digits 0 or not. This will prevent you from printing leading zeroes.
Your code fails this case :
3
0 0 1
actual : 0
your : 00
This may be the case for test case 14 where your code failed
Bug 3 :
Again when you did this :
for(int i=n-1;i>=0;i–)
{
if(i!=pos1 and i!=pos2)
cout << a[i];
}
You should take care about if all the other digits are 0 or not.
Your code fails this test :
4
0 0 1 1
actual : 0
your : 00
This may be the case for test case 14 where your code failed
Bug 4 :
Again here :
for(int i=n-1;i>=0;i–)
{
if(i!=ps)
cout << a[i];
}
You should check whether the other digits are all zero or not.
Your code fails this test :
3
0 0 2
actual : 0
your : 00
This may be the case for test case 14 where your code failed
I hope there are no more bugs .Hope this helps . Don’t be disheartened by all these bugs. You’ll obviously do better and learn from your mistakes Good luck
Thanks for pointing out my mistakes.
Finally solved it.
Great Job !! =D Carry on
