Idea: Tree Array Analysis: 1. The question is given to the nheaded bull's hearing v [I]. it is now stipulated that if I and j are to communicate with each other, the energy consumed is dis (I, j) * max (v [I]. v [j]). Now I want to know the total

There is a nheaded ox, each of which has a coordinate and harmonic adjustment value (x, V). the energy required for communication between the two cows is their distance multiplied by the largest tone value, how much energy does it take for any two

MySQL database sub-partition tutorial A child partition is a second split for each partition in a partitioned table. For example, consider the following create TABLE statement: CREATE TABLE ts (id INT, purchased DATE) PARTITION by RANGE (year (purchased)) Subpartition by HASH (To_days (purchased)) Subpartitions 2 ( PARTITION p0 VALUES less THAN (1990), PARTITION p1 VALUES less THAN (2000), PARTITION p2 VALUES less THAN MAXVALUE ); The table
