java - NIO: OP_READ and not reading all data; does OP_READ remain in ready set? -


imagine socket channel 32kb socket receive buffer.

24kb of data being received , op_read set in ready set , io thread gets notified process incoming data.

normally socketchannel.read called bytebuffer able store content of socket receive buffer.

but question:

what happens when bytebuffer isn't big enough read data,e.g. bytebuffer of 16kb, , therefor 8kb remain in socket receive buffer. op_read removed ready set or op_read remain in ready set long data remains in socket-buffer of socket.

normally socketchannel.read called bytebuffer able store content of socket receive buffer.

no isn't. called bytebuffer large enough receive whatever application ready receive @ time.

what happens when bytebuffer isn't big enough read data,e.g. bytebuffer of 16kb, , therefor 8kb remain in socket receive buffer. op_read removed ready set

no.

or op_read remain in ready set long data remains in socket-buffer of socket.

yes.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
