题目描述
Watson gives Sherlock an array of integers. Given the endpoints of an integer range, for all $M$ in that inclusive range, determine the minimum( abs(arr[i]-M) for all $1\leq i\leq|arr|$) ). Once that has been determined for all integers in the range, return the $M$ which generated the maximum of those values. If there are multiple $M$'s that result in that value, return the lowest one.
For example, your array $arr=[3,5,7,9]$ and your range is from $p=6$ to $q=8$ inclusive.
M |arr[1]-M| |arr[2]-M| |arr[3]-M| |arr[4]-M| Min
6 3 1 1 3 1
7 4 2 0 2 0
8 5 3 1 1 1
We look at the Min column and see the maximum of those three values is $1$. Two $M$'s result in that answer so we choose the lower value, $6$.
Function Description
Complete the sherlockAndMinimax function in the editor below. It should return an integer as described.
sherlockAndMinimax has the following parameters:
-
arr: an array of integers
-
p: an integer that represents the lowest value of the range for $M$
-
q: an integer that represents the highest value of the range for $M$
Input Format
The first line contains an integer $n$, the number of elements in $arr$.
The next line contains $n$ space-separated integers $i$.
The third line contains two space-separated integers $p$ and $q$, the inclusive endpoints for the range of $M$.
Constraints
$1\leq n\leq10^2$
$1\leq ar r[i]\leq10^9$
$1\leq p\leq q\leq10^9$
Output Format
Print the value of $M$ on a line.
Sample Input
3
5 8 14
4 9
Sample Output
4
Explanation
$arr=[5,8,14],range=[4-9]$
M |arr[1]-M| |arr[2]-M| |arr[3]-M| Min
4 1 4 10 1
5 0 3 9 0
6 1 2 8 1
7 2 1 7 1
8 3 0 6 0
9 4 1 5 1
For $M=4,6,7$, or $9$, the result is $1$. Since we have to output the smallest of the multiple solutions, we print $4$.
