## Code
### Java

class Solution {
    public int[][] sortTheStudents(int[][] score, int k) {
        Arrays.sort(score, (a, b) -> b[k] - a[k]);
        return score;
    }
}

### Python
The ```sort()``` method doesn't return any value. Rather, it changes the original list
If you want a function to return the sorted list rather than change the original list, use ```sorted()```

class Solution:
    def sortTheStudents(self, score: List[List[int]], k: int) -> List[List[int]]:
        return sorted(score, key = lambda a : -a[k])

class Solution:
    def sortTheStudents(self, score: List[List[int]], k: int) -> List[List[int]]:
        score.sort(key = lambda a : -a[k])
        return score
