SPOJ Problem Set (classical)
3459. SkyScrapers
Problem code: CEPC08B

In a seaside village, there is an avenue of skyscrapers. Each skyscrapers is 100m wide and has certain
height. Due to very high price of parcels, any two consecutive skyscrapers are adjacent. The avenue lies close to the beach so the street is exactly at the sea level.
Unfortunately, this year, due to the global warming, the sea level started to increase by one meter
each day. If the skyscraper height is no greater than the current sea level, it is considered ﬂooded.
A region is a maximal set of nonﬂooded, adjacent skyscrapers. This term is of particular importance, as
it is suﬃcient to deliver goods (like current, carrots or cabbages) to any single skyscraper in each region.
Hence, the city major wants to know how many regions there will be in the hard days that come.
An example of an avenue with 5 skyscrapers after 2 days is given below.
Input
The input contains several test cases. The ﬁrst line contains an
integer t
(t ≤ 15) denoting the number
of test cases. Then t
test cases follow. Each of them begins with a line containing two
numbers n
and
d (1 ≤ n, d
≤ 10^{6}), n
is the number of skyscrapers and d
is the number of days which the major wants
to query. Skyscrapers are numbered from left to right. The next line
contains n integers h_{1}, h_{2},
. . . , h_{n}
where 1 ≤ h_{i} ≤ 10^{9} is the
height of skyscraper i.
The third line of a single test case contains d numbers
t_{j} such that 0 ≤ t_{1}
< t_{2} < . . . < t_{d−1}
< t_{d} ≤ 10^{9}.
Output
For each test case output d numbers r_{1}, r_{2},
. . . , r_{d}, where r_{j} is
the number of regions on day t_{j} .
