 In this post, we will learn how to find the Average of N numbers in Java.

Java Program to find the Average of N numbers

Write a Java program to find the Average of N numbers, take all the n numbers as input.

Example 1:
Input: number of elements is = 5
       elements = 1, 2, 3, 4, 5
Output: 3
Explanation: 
  avg = (1 + 2 + 3 + 4 + 5) / 5 = 3

Java Program: 

// Java program to find Average of N numbers

import java.util.Scanner;

public class Main {
	
	public static void main(String[] args) { 
		Scanner sc = new Scanner(System.in);
		
		System.out.println("How many numbers are there?");
		int num = sc.nextInt();
		
		double sum = 0;
		for(int i = 0; i < num; i++) {
			System.out.println("Enter " + (i+1) + " element: ");
			int n = sc.nextInt();
			sum = sum + n;
		}
		
		// find avg
		double avg = sum / num;
		System.out.print("Average of " + num + " numbers is: " + avg);
		
		sc.close();
	}
}

Output: 

How many numbers are there?
5
Enter 1 element: 
1
Enter 2 element: 
2
Enter 3 element: 
3
Enter 4 element: 
4
Enter 5 element: 
5
Average of 5 numbers is: 3.0

N-th Tribonacci Number Solution - The Coding Shala

Home >> Programming >> N-th Tribonacci Number  Hey there, welcome back to another post. In this post, we will learn how to solve the N-th Tribonacci Number problem and will implement its solution in Java. N-th Tribonacci Number Problem Statement The Tribonacci sequence Tn is defined as follows: T0 = 0, T1 = 1, T2 = 1, and Tn+3 = Tn + Tn+1 + Tn+2 for n >= 0. Given n, return the value of Tn.  Example 1:  Input: n = 4 Output: 4 Explanation: T_3 = 0 + 1 + 1 = 2 T_4 = 1 + 1 + 2 = 4 N-th Tribonacci Number Java Solution using Bottom-Up DP This problem is similar to the Fibonacci series. We can solve it using the Bottom-Up approach of dynamic programming. Time Complexity: O(n) Space Complexity: O(n) The space complexity can be reduced to O(1) by using variables to store the previous three values instead of using an array. Java Program:  class Solution { public int tribonacci( int n) { if (n == 0) return 0; if (n == 1 || n == 2

Find Second Smallest Element in the Array - The Coding Shala

Home >> Programming >> Find Second Smallest Element in the Array  Hey there, welcome back to another post. In this post, we will learn how to find the second smallest number in the array in Java. Find Second Smallest Element in the Array Problem Statement You have given an integer array, return the second smallest element from the array if exists else return no second smallest element exists. Example 1:  Input: [1, 4, 2, 7, 90, -1, -4] Output: -1 Find Second Smallest Element in the Array Solution using Single Iteration Approach By using the below steps we can find the second smallest element in the array by using a single iteration: Initialize two variables first and second for smallest and second smallest numbers and the initial value will be Integer.MAX_VALUE. Traverse the array and check if the current element is smaller than the smallest element then update both first and second. If the current element is between first and second then only update the seco

New Year Chaos Solution - The Coding Shala

Home >> Programming Questions >> New Year Chaos New Year Chaos Problem Solution In this post, you will learn how to solve New Year Chaos Problem and implement its solution in Java. Problem:   It's New Year's Day and everyone's in line for the Wonderland rollercoaster ride! There are a number of people queued up, and each person wears a sticker indicating their initial position in the queue. Initial positions increment from at the front of the line to at the back.  Any person in the queue can bribe the person directly in front of them to swap positions. If two people swap positions, they still wear the same sticker denoting their original places in line. One person can bribe at most two others.  For Example, if n=8 and Person 5 bribes Person 4, the queue will look like this: 1,2,3,5,4,6,7,8. Fascinated by this chaotic queue, you decide you must know the minimum number of bribes that took place to get the queue into its current state. Input:
