Simple Array Sum
Problem Statement :
Given an array of integers, find the sum of its elements.
For example, if the array ar = [1,2,3], 1+2+3 = 6 , so return 6
.
Function Description
Complete the simpleArraySum function in the editor below. It must return the sum of the array elements as an integer.
simpleArraySum has the following parameter(s):
ar: an array of integers
Input Format
The first line contains an integer, n, denoting the size of the array.
The second line contains n space-separated integers representing the array's elements.
Constraints 0 < n, a[i] < = 1000
Output Format
Print the sum of the array's elements as a single integer.
Solution :
Solution in C :
In C :
int simpleArraySum(int ar_count, int* ar) {
int i;
int sum = 0;
for(i=0;i < ar_count;i++)
{
sum = sum + ar[i];
}
return sum;
}
In Python3:
n = int(input())
nums = list(map(int, input().split()))
sum = 0
for num in nums:
sum += num
print(sum)
In C++ :
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
int main() {
unsigned long long int N, Sum = 0, i, Num;
cin>>N;
for (i = 1 ; i <= N ; i++)
{
cin>> Num;
Sum += Num;
}
cout<<Sum<<endl;
return 0;
}
In Java :
import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

You are a waiter at a party. There is a pile of numbered plates. Create an empty answers array. At each iteration, i, remove each plate from the top of the stack in order. Determine if the number on the plate is evenly divisible ith the prime number. If it is, stack it in pile Bi. Otherwise, stack it in stack Ai. Store the values Bi in from top to bottom in answers. In the next iteration, do the

A queue is an abstract data type that maintains the order in which elements were added to it, allowing the oldest elements to be removed from the front and new elements to be added to the rear. This is called a First-In-First-Out (FIFO) data structure because the first element added to the queue (i.e., the one that has been waiting the longest) is always the first one to be removed. A basic que

You are given Q queries. Each query consists of a single number N. You can perform any of the 2 operations N on in each move: 1: If we take 2 integers a and b where , N = a * b , then we can change N = max( a, b ) 2: Decrease the value of N by 1. Determine the minimum number of moves required to reduce the value of N to 0. Input Format The first line contains the integer Q.
