s.pop();
if(!s.empty())
curr=a[t]*(-s.top()+i-1);

@dakshi please share the ide link of your code.

@dakshi Your code seems to be correct. Please once try it submitting after changing int to long long int.

You will also need to convert your array to long long because for calculating the answer their multiplication is taking place.
I have done that change in your code, you can see at https://ide.codingblocks.com/s/224522
