Given an array arr[] of size N, The duty is to seek out the utmost and the minimal quantity within the array.
Examples:
Enter: arr[] = {1, 2, 3, 4, 5}
Output: Most is: 5
Minimal is: 1
Clarification: The utmost of the array is 5
and the minimal of the array is 1.Enter: arr[] = {5, 3, 7, 4, 2}
Output: Most is: 7
Minimal is: 2
Method 1(Grasping): The issue could be solved utilizing the grasping strategy:
The answer is to check every array component for minimal and most components by contemplating a single merchandise at a time.
Comply with the steps to resolve the issue:
- Create a variable mini/maxi and initialize it with the worth at index zero of the array.
- Iterate over the array and examine if the present component is larger than the maxi or lower than the mini.
- Replace the mini/maxi component with the present component in order that the minimal/most component is saved within the mini/maxi variable.
- Return the mini/maxi variable.
Beneath is the implementation of the above concept:

Most is: 5 Minimal is: 1
Time Complexity: O(N)
Auxiliary House: O(1)
Method 2(Library Perform): The issue could be solved utilizing the library features supplied in numerous programming languages.
We will use min_element() and max_element() to seek out the minimal and most components of the array in C++.
Beneath is the implementation of the above concept:
C++

Most is: 5 Minimal is: 1
Time Complexity: O(N)
Auxiliary House: O(1)
Method 3(Minimal comparisons): To unravel the issue with minimal variety of comparisons, observe the under steps:
- If N is odd then initialize mini and maxi as the primary component.
- If N is even then initialize mini and maxi as minimal and most of the primary two components respectively.
- For the remainder of the weather, choose them in pairs and examine
- Most and minimal with maxi and mini respectively.
The overall variety of comparisons might be:
If N is odd: 3*(N – 1)/2
If N is even: 1 Preliminary comparability for initializing min and max, and three(N – 2)/2 comparisons for remainder of the weather
= 1 + 3*(N – 2) / 2 = 3N / 2 – 2
Beneath is the implementation of the above concept:
