Oracle database, the field is VARCHAR2 type string, but in fact, the number is stored, the order by the sort result, there must be a problem

About "Reverse Order Number"

Yesterday, we made a qualifying round for Tsinghua. Shen Da, Liang laoda, and Xiao cross each handled a single question, and almost fell out of 60. I did B and F, where F is about the number of reverse orders. The complexity is that the worst complexity of nlog2n + Mn may be reduced to O (N ^ 2 ). But the result I submitted is not TLE, but MLE and RE. I really don't know if there is a problem with the Tsinghua discriminant system or my program. In sho
