Can someone help me debug the code of 'Beautiful Array' (BTAR)?

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:

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:

1 1 2 1 1 2

Expected output: 4 [{(1+1)+2}+{(1+1)+2}].
Your code gives: no output
Check it here:
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.
