consider a TCP connection with a slow start phase with an initial threshold value be 64 KB when 3 duplicate acknowledgements is received. The receiver advertised window size is 32 KB and the maximum segment size used is 2kB. The first transmission attempt is numbered at 0 and all transmission attempts are successful except for the timeout on attempt number 4.sender window size at attempt 12 ______.

can someone plz verify my solution
