Problem Description
In Land waterless, water is a very limited resource. People always fight for the biggest source of water. Given a sequence of water sources with
a1,a2,a3,...,anrepresenting the size of the water source. Given a set of queries each containing
2integers
land
r, please find out the biggest water source between
aland
ar.
Input
First you are given an integer
T(T≤10)indicating the number of test cases. For each test case, there is a number
n(0≤n≤1000)on a line representing the number of water sources.
nintegers follow, respectively
a1,a2,a3,...,an, and each integer is in
{1,...,106}. On the next line, there is a number
q(0≤q≤1000)representing the number of queries. After that, there will be
qlines with two integers
land
r(1≤l≤r≤n)indicating the range of which you should find out the biggest water source.
Output
For each query, output an integer representing the size of the biggest water source.
Sample Input
3 1 100 1 1 1 5 1 2 3 4 5 5 1 2 1 3 2 4 3 4 3 5 3 1 999999 1 4 1 1 1 2 2 3 3 3
Sample Output
100 2 3 4 4 5 1 999999 999999 1

題目大意:給出n個水池的水量,找出區間內最大的水量。
求區間最值,正常都采用線段樹的方法,但是這題數據量不大,所有暴力就過了~
詳見代碼。
