C program to print all repeated elements in an array and also print the count of repeated numbers

 Write a program to print all repeated elements in an array and also print the count of repeated numbers

Note: Hope it helps you! Please note that all the intentions are to clear the doubt of how to solve it in java. So, please try to give it a chance at least before using this. If you face any discrepancy please contact us. Thank you!

Example:

input:
Enter the number of element: 4
Enter Elements: 10
20
10
20
output:
The duplicate number is: 10
The duplicate number is: 20
The total number of the duplicate element is: 2

Algorithm of this program:
  1. Initially, we define the size of the array.
  2. Then, take a user-input size of the array and scan the element of the array.
  3. For finding the duplicate number in the array we have to run two for loops.
  4. The first for loop scan all elements from 0 index
  5. The next for loops run from i+1 so that it checks all the duplicate elements.
  6. If any duplicate element is found, we print the duplicate number and count it.
  7. At last, we print the count of all the duplicate numbers present in the array.
  8. The return type of the main function is int so, in the last, we return 0.

Program of the problem:

//Write a program to print all repeated elements in an array and also print the count of //repeated numbers
#include <stdio.h>
#define SIZE 100  
int main(){
    int arr[SIZE];
    int size;
    int count = 0;
    printf("Enter the number of elements in array: ");
    scanf("%d", &size);
    printf("Enter the value of elements in array: ");
    for(int i=0; i<size; i++){
        scanf("%d", &arr[i]);
    }
    for(int i=0; i<size; i++){
        for(int j=i+1; j<size; j++){
            if(arr[i] == arr[j]){
                printf("The duplicate numbers is: %d\n", arr[i]);
                count++;
                break;
            }
        }
    }
    printf("\nTotal number of duplicate elements found in array = %d", count);
    return 0;
}

Output:
output of above program



Hope! it helps 🙏

 Java Stdin and Stdout II Hackerrank Solution in Java Problem-4:- In this challenge, you must read an  integer , a  double , and a  String  from stdin, then print the values according to the instructions in the  Output Format  section below. To make the problem a little easier, a portion of the code is provided for you in the editor. Note:  We recommend completing  Java Stdin and Stdout I  before attempting this challenge. Input Format There are three lines of input: The first line contains an  integer . The second line contains a  double . The third line contains a  String . Output Format There are three lines of output: On the first line, print  String:  followed by the unaltered  String  read from stdin. On the second line, print  Double:  followed by the unaltered  double  read from stdin. On the third line, print  Int:  followed by the unaltered  integer  rea...

Java Output Formating Hackerrank Solution in Java

By
  Java Output Formating Hackerrank Solution in Java Problem-5:- Java's  System.out.printf  function can be used to print formatted output. The purpose of this exercise is to test your understanding of formatting output using  printf . To get you started, a portion of the solution is provided for you in the editor; you must format and print the input to complete the solution. Input Format Every line of input will contain a  String  followed by an  integer . Each  String  will have a maximum of   alphabetic characters, and each  integer  will be in the inclusive range from   to  . Output Format In each line of output there should be two columns: The first column contains the  String  and is left justified using exactly   characters. The second column contains the  integer , expressed in exactly   digits; if the original input has less than three digits, you must pad your outp...

  W elcome to Java! Hackerrank Solution in Java Problem-1:- Welcome to the world of Java! In this challenge, we practice printing to stdout. The code stubs in your editor declare a  Solution  class and a  main  method. Complete the  main  method by copying the two lines of code below and pasting them inside the body of your  main  method. System . out . println ( "Hello, World." ); System . out . println ( "Hello, Java." ); Input Format There is no input for this challenge. Output Format You must print two lines of output: Print  Hello, World.  on the first line. Print  Hello, Java.  on the second line. Sample Output Hello, World. Hello, Java. Solution:- public   class   Solution   {      public   static   void   main ( String []   args )   {          /* Enter your code here. Print output...
