Subtask is against the constrain


subtask1 and constrain 3 vary from each other which one should be applied

  • 1≤T≤100
  • 1≤N≤103
    *ai∈{5,10,15} for each valid i


Subtask #1 (40 points): ai∈{5,10} for each valid i

It says that for 1st subtask the elements in array will be 5 and 10 only.
For second subtask the elements will be 5,10,15.
If you want to get correct answer (100points) you need to consider ai belongs to 5,10,15.

Hope it helps. Happy coding.

for subtask 1 just consider 5 and 10 but for all subtask consider 5 10 15

I have tried it but I didn’t get the complete points
