Known integrals, if the level and integral have a certain regularity, you can quickly determine the user's level according to the algorithm;So there is no regularity, so how to quickly determine the level?

Known integ
ranging from 1C),SRepresents the number of streets andQIs the number of queries.
Each of the nextSLines contains three integers:C1,C2 andDIndicating that the average sound intensity level on the street connecting the crossingsC1 andC2 () isDDecibels.
Each of the nextQLines contains two integersC1 andC2 () asking for the minimum sound intensity level you must be able to tolerate in order to get from crossingC1 to crossingC2.
The input will terminate with three zeros formC,SAndQ.
Output

In MS-SQLServer 2005, you can use the combine operator to convert rows and columns. However, you must use the case when then else end statement in earlier versions.
The student renewal table is used as an example below:

rollup () and cube ().
Rollup (): enables grouping results to contain subtotal and total information, and can input multiple columns of fieldsCube (): subtotal is performed for each column passed as a parameter. The advantage is displayed when multiple columns are passed in.Example:Select id, sum (mount) from tt group by rollup (id );Id sum (MOUNT)--------------------1 602 1503 2404 2105 4401100Select id, sum (mount) from tt group by cube (id );Id su
