C - Covered Points Count

CodeForces - 1000C

You are given nn segments on a coordinate line; each endpoint of every segment has integer coordinates. Some segments can degenerate to points. Segments can intersect with each other, be nested in each other or even coincide.

Your task is the following: for every k∈[1..n]k∈[1..n], calculate the number of points with integer coordinates such that the number of segments that cover these points equals kk. A segment with endpoints lili and riri covers point xx if and only if li≤x≤rili≤x≤ri.

Input

The first line of the input contains one integer nn (1≤n≤2⋅1051≤n≤2⋅105) — the number of segments.

The next nn lines contain segments. The ii-th line contains a pair of integers li,rili,ri (0≤li≤ri≤10180≤li≤ri≤1018) — the endpoints of the ii-th segment.

Output

Print nn space separated integers cnt1,cnt2,…,cntncnt1,cnt2,…,cntn, where cnticnti is equal to the number of points such that the number of segments that cover these points equals to ii.

Examples

Input

30 31 33 8

Output

6 2 1

Input

31 32 45 7

Output

5 2 0

Note

The picture describing the first example:

img

Points with coordinates [0,4,5,6,7,8][0,4,5,6,7,8] are covered by one segment, points [1,2][1,2] are covered by two segments and point [3][3] is covered by three segments.

The picture describing the second example:

img

Points [1,4,5,6,7][1,4,5,6,7] are covered by one segment, points [2,3][2,3] are covered by two segments and there are no points covered by three segments.

题意：

给你n个线段

让你输出有多少个点被1~n个线段覆盖？

思路：

将线段拆成点，左端点权值为1，右端点权值为-1，离散化端点之后从左往右扫，过程中维护左端点和当前区间被多少个线段覆盖，统计答案就行了。

注意：

因为l~r线段中包括的点数是r-l+1，所以我们可以直接r++

map会根据firstkey 即ll排好序，所以可以直接for（auto : T）
