Finding the maximum & minimum element in an array

Reading Time:- 1 min 55 sec

BY TEJAS

Finding the maximum & minimum element in an array is a very simple program. And this program is asked in many interviews. So the following explanation will help you to understand how to tackle this simple program.

Eg:-
a[ ] = {4, 5, 9, 2, 35, 7, 3, 1}
maximum Element = 35
Minimum Element = 1

C Program
C++ Program
Java Program
Python Program

Explanation:

First, we have created an array called a[] in which some elements have been passed. Then the size of an array is stored in the variable n. Then the first element of an array is stored in the variables min and max.

Then we have created a for loop in which if the value of a[i] is greater than the variable max then the value of a[i] should be stored in the variable max & if the value of a[i] is less than the variable min So we should store the value of a[i] in min.

The for loop will continue to be executed until the condition is satisfactory & the smallest and largest element in the whole array will be stored in the variables min and max.

And after that, we will simply print the values of min and max variables.

C Program:

To find the maximum and minimum element in an array.

                            
    #include<stdio.h>
    int main()
    {
        int a[] = {20, 2, 5, 9, 23, 7, 54};
        int n = sisizeof(a[0]);
        int min = a[0];
        int max = a[0];
        for(int i=0; i<n; i++)
        {
            if(a[i] > max)
                max = a[i];
                                                    
            else if(a[i] < min)
                min = a[i];
        }
        printf("Minimum Element in an Array is : %d", min);
        printf("Maximum Element in an Array is : %d", max);
    }

C++ Program:

To find the maximum and minimum element in an array.

                            
    #include <iostream>
    using namespace std;
                                    
    int main()
    {
        int a[] = {20, 2, 5, 9, 23, 7, 54};
        int n = sizeof(a) / sizeof(a[0]);
        int min = a[0];
        int max = a[0];
        for(int i=0; i<n; i++)
        {
            if(a[i] > max)
                max = a[i];
                                            
            else if(a[i] < min)
                min = a[i];
        }
        cout << "Minimum Element in an Array is : " << min;
        cout << " Maximum Element in an Array is : " << max;
    }

Java Program:

To find the maximum and minimum element in an array.

                            
    public class MinMaxArray {
        public static void main(String[] args) {
            int[] a = {20, 2, 5, 9, 23, 7, 54};
            int n = (int)a.length;
            int min = a[0];
            int max = a[0];
            for(int i = 0; i < n; i++) {
                if(a[i] > max) {
                    max = a[i];
                } else if(a[i] < min) {
                    min = a[i];
                }
            }
            System.out.println("Minimum Element in an Array is : " + min);
            System.out.print("Maximum Element in an Array is : " + max);
        }
    }

Python Program:

To find the maximum and minimum element in an array.

                            
    a = [20, 2, 5, 9, 23, 7, 54]
    n = len(a)
    min = max = a[0]
    for i in range(n):
        if a[i] < max:
            max = a[i]
        elif a[i] < min:
            min = a[i]
    print("Minimum Element in an Array is : ", min)
    print("Maximum Element in an Array is : ", max)
