I would suggest making the functions inline. You are passing an array to a function in checkIfLeftEqualToRight, which is as it is expensive, and on top of it the maximum array size is 10^5, adding all the more to the running time of the program. Tell me if it works.
the code has been written in java and sorry for my lack of knowledge but i never heard inline function in java. i tried to look up but didnt find much answere to that. apart from it from my understanding of java , we are passing the refrence of the array object but not the object itself so method is just extension of seprated code. i might be wrong.. in such case i would welcome updated information.
apart from it the logic that i have written it works in two 4 cases while fails in 3. in two timed out is there while in 1 it fails. i am trying to understand what am i doing wrong here logically.
I apologize for not being clear enough. I meant substitute the function call with the function itself. You might have to make slight modifications in the code, which you should be able to do with a little effort. In the else part of your checkifleftequaltoright, you are calling the gettotalsum function, and the call is within the for loop. I think that could be a cause of problem. Try substituting the function call with the function code and see if it works. Have you asked the experts while posting your question?
Tip: Always format your code while you ask a question. The greater the readability of your code, the more likely you get an answer. I have formatted it this time for you. I hope somebody else answers, if my response is not good enough.

Hi , Thanks for the reply.

Please accept my thanks for answering to my queries as well as helping me out :)
You're welcome. Is your solution now passing all test cases?
unfortunately no , the issue is with logic i think. i am solving other puzzles in the mean while and letting my mind cool down for this logic :).
