I am getting WA.
I tried many custom cases but not able to find the case giving wrong answer.
Please help me!
Here is my code:

if(a[1]!=0)
{
c+=2*(a[1]/4);
a[1]=4;
}
if(a[3]!=0)
{
c+=2*(a[3]/4);
a[3]=4;
}
in this part of your code you should do c+=3 *(a[1]/4) and 3 *(a[3]/4) instead as it would take 3 steps to combine 4 1s and 4 3s

Hey @assassin28,
Try this TC:
6
1 1 2 1 1 2
Expected output: 4 [{(1+1)+2}+{(1+1)+2}].
Your code gives: no output
Check it here: https://code.hackerearth.com/88cca6k?key=62e360ba986a5e7ae749f9f4a7a1fbc4
Consider modifying last elif or/and add another conditional expression.
Hope this helps!

Thank you!
That was the exact problem.
Yes,there was a problem in last elif as told by @mohitkurani98.
And your test case helped too.
