I do understand the query, i.e, query of type 1 A means adding 1 to the value at A, query of type 2 X means how many queue has pilgrims of length >= X and query of type 3 Y means to subtract 1 from each of the queues having >= Y pilgrims. I'm just not sure how to process my original arrays so that I can easily update using BIT. Any hint will be really appreciated.
