As there are numerous queries of the order of 10^5, you have to give the result of each query in at most O(log(N)) time. So as this problem is of type range update, range query the best approach to solve the problem of FLIPCOIN is by using Segment Trees. Its construction time if O(N*log(N)). and gives the results of range queries in O(log(N)). Read these two links if you are new to this concept :
