Given two sequences of length n \ (A \), \ (B \). There are m available actions \ ((t_i,u_i,v_i) \). $$t$$ represents the type of operation. When \ (t=1 \), it means that both \ (a {u_i} \) and \ (a {v_i} \) can be \ (+ 1 \); When \ (t=2 \), it means that one of \ (a {u_i} \) and \ (a {v_i} \) can be \ (+ 1 \) and the other \ (- 1 \); There is ...
