This question uses the counting sort idea to solve the problem.Note this question. It seems that using direct sorting, and then searching for rank will be directly judged by Wa, a strange judgment system.Because the value range is 0 to 100, it is very small, and student number is very large, it is natural to use counting sort.# Include

Collection is not recommended for cooking. For some friends who make collection websites, they ask "How to rank collection sites?

This topic compares the size of the array composition character, so it is natural to think about the large number of problems. So the whole process is to use strings to compare and sa
