Array

You are given an array of positive integers arr. Perform some operations (possibly none) on arr so that it satisfies these conditions:
There are 2 types of operations that you can perform any number of times:
Return the maximum possible value of an element in arr after performing the operations to satisfy the conditions.
Examples
Example 1
Input: arr = [2,2,1,2,1]
Output: 2
Explanation:
We can satisfy the conditions by rearranging arr so it becomes [1,2,2,2,1].
The largest element in arr is 2.
Example 2
Input: arr = [100,1,1000]
Output: 3
Explanation:
One possible way to satisfy the conditions is by doing the following:
1. Rearrange arr so it becomes [1,100,1000].
2. Decrease the value of the second element to 2.
3. Decrease the value of the third element to 3.
Now arr = [1,2,3], which satisfies the conditions.
The largest element in arr is 3.
Example 3
Input: arr = [1,2,3,4,5]
Output: 5
Explanation: The array already satisfies the conditions, and the largest element is 5.
Constraints
1 <= arr.length <= 105
1 <= arr[i] <= 109
