algorithm - Partition into sub-sequences that XOR to 0 -


given array [a1, a2 ...an], partition sub-sequences maximizes quantity of xor 0. return count of sub-sequences.

examples:

input    : 3 0 2 2 partition: [3] [0] [2 2] output   : 2 members  : [0] [2 2]  input    : 5 3 1 2 5 6 3 7 4 0 8 partition: [5] [3 1 2] [5 6 3] [7 4] [0] [8] output   : 3 members  : [3 1 2] [5 6 3] [0]

i searched tips on google , languange engine, can not hint.

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
