CVJETICI - Cvjetici
On a faraway planet, strange plants with two stems can be found. Every plant on the planet can be described by three numbers: the x-coordinates of the stems L and R, and the height H at which the stems are connect. The image depicts a plant with L=2, R=5 and H=4.
Every day a new plant grows on the planet. The plant that grows on day 1 is of height 1, and every subsequent plant is one higher than the previous one.
When a stem of a new plant intersects the horizontal segment of another plant, a small flower grows (if one wasn't there already). If segments merely touch in a point, a flower will not grow there. The following images are a visualization of the first example.
Write a program that, given the coordinates of all plants, calculates the number of new flower every day.
The first line contains an integer N (1 ≤ N ≤ 100 000), the number of days.
Each of the following N lines contains two integers L and R (1 ≤ L < R ≤ 100 000), the coordinates of the stems of a plant.
Output N lines, the number of new flowers after each plant grows.

1d BIT problem
my 100th..... :) :)
nice problemLast edit: 2015-04-30 21:55:49
WA in 10th test cases, please give any suggestion for corner cases.
easy but enjoyed solving it
@nour samir: Do not ask for spoilers in the comments section.
awesome problem , learned a lot!
Actually, Input sequence and content of the problem does not match! First drawn plant must be the earliest plant, not the last grown plant!
