If anyone could help how can I optimise my code so that it could be accepted.It is working fine but is giving TLE for #12 testcase (1 2000).

Can someone explain eugene one. I am unable to get it. I was relating this to count arrays with sum zero and using that approach. and then subtracting n(n+1)/2-count.

But I am not able to figure out how to include in count those subarrays of the given array whose subarrays are also not good.
