Simple Array Sum C and Java Solution

Problem-2
Given an array of  integers, can you find the sum of its elements?
Input Format
The first line contains an integer, , denoting the size of the array. 
The second line contains  space-separated integers representing the array's elements.
Output Format
Print the sum of the array's elements as a single integer.
Sample Input
6
1 2 3 4 10 11
Sample Output
31
Explanation
We print the sum of the array's elements, which is: .
Solution
// C code Solution

int main(){
    int n,i,sum=0; 
    scanf("%d",&n);
    int arr[n];
    for(int arr_i = 0; arr_i < n; arr_i++){
       scanf("%d",&arr[arr_i]);
    }
    while(i
// Java Solution

public class SimpleArraySum {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        int number = sc.nextInt();
        int sum=0;

Solve Me First C Solution

Problem : Welcome to HackerRank! The purpose of this challenge is to familiarize you with reading input from  stdin  (the standard input stream) and writing output to  stdout  (the standard output stream) using our environment. Review the code provided in the editor below, then complete the  solveMeFirst  function so that it returns the sum of two integers read from stdin. Take some time to understand this code so you're prepared to write it yourself in future challenges. Select a language below, and start coding! Input Format Code that reads input from stdin is provided for you in the editor. There are 2  lines of input, and each line contains a single integer. Output Format Code that prints the sum calculated and returned by  solveMeFirst  is provided for you in the editor. Solution: int solveMeFirst(int a, int b) { // Hint: Type return a+b; below return a+b; } int main() { int num1,n...

Killjee and easy problem

Killjee is solving an easy problem. Given an array  a a  containing  N N  positive integers. You need to find the magic value of the array. Magic value of an array is  ∑ N i = 1 ( b i i ) ∑ i = 1 N ( b i i ) . where,  b i b i  is number of set bits of  a i a i . Find and print the answer  Modulo   ( 10 10 + 11 ) ( 10 10 + 11 ) INPUT CONSTRAINTS 1 ≤ N ≤ 10 5 1 ≤ N ≤ 10 5 1 ≤ a i ≤ 10 9 1 ≤ a i ≤ 10 9 INPUT FORMAT First line of input contains a single integer  N N . Next line contains  N N  space separated integers, elements of array  a a . OUTPUT FORMAT Output a single integer, magic value of the array. Sample Input 3 1 2 4 Sample Output 3 Explanation b [ 1 ] = 1 , b [ 2 ] = 1 b [ 1 ] = 1 , b [ 2 ] = 1  and  b [ 3 ] = 1 b [ 3 ] = 1  so, summation of  b [ i ] i b [ i ] i  =  1 + 1 + 1 = 3 1 + 1 + 1 = 3 . Note:  Your code should be able to c...

Compare the Triplets C Solution

Problem : Alice and Bob each created one problem for HackerRank. A reviewer rates the two challenges, awarding points on a scale from   to   for three categories:  problem clarity ,  originality , and  difficulty . We define the rating for Alice's challenge to be the triplet  , and the rating for Bob's challenge to be the triplet  . Your task is to find their  comparison scores  by comparing   with  ,   with  , and   with  . If  , then Alice is awarded   point. If  , then Bob is awarded   point. If  , then neither person receives a point. Given   and  , can you compare the two challenges and print their respective comparison points? Input Format The first line contains   space-separated integers,  ,  , and  , describing the respective values in triplet  .  The second line cont...
