题目描述
- 老阅读题了= =,第一遍看题的时候一脸懵逼
- 但其实代码就6行(嘿嘿)


思路 && 代码
class Solution {
public int[][] reconstructQueue(int[][] people) {
Arrays.sort(people, (p1, p2) -> ((p1[0] == p2[0] ? p1[1] - p2[1] : p2[0] - p1[0])));
List<int[]> ans = new ArrayList<>();
for(int[] temp : people) {
ans.add(temp[1], temp);
}
return ans.toArray(new int[ans.size()][]);
}
}
class Solution {
public int[][] reconstructQueue(int[][] people) {
Arrays.sort(people, (p1, p2) -> ((p1[0] == p2[0] ? p1[1] - p2[1] : p2[0] - p1[0])));
List<int[]> ans = new ArrayList<>();
for(int[] temp : people) {
ans.add(temp[1], temp);
}
return ans.toArray(new int[ans.size()][]);
}
}
二刷
class Solution {
public int[][] reconstructQueue(int[][] people) {
Arrays.sort(people, (int[] a, int[] b) -> (a[0] == b[0] ? a[1] - b[1] : b[0] - a[0]));
List<int[]> ans = new ArrayList<>();
for(int[] temp : people) {
ans.add(temp[1], temp);
}
return ans.toArray(new int[ans.size()][]);
}
}
