Problem
Write a method to find the sum of all the elements in the integer Array.
Sum of Array
Problem Analysis:-
- Input: The method will take Integer Array as an input.
- Process:
- Declare an int variable sum and initialize with value 0
- Traversed through the array’s elements using for loop
- Inside for loop: Add each element value to the sum variable
- After traversing return the sum value.
- Output: Sum of all the elements in the Array
Solution:-
Output:-
Analysis:- Since all the elements are traversed the Time complexity is O(n)
Code:-
public class SumOfArray { public static int GetSumOfArray(int[] intArray) { int sum = 0; for (int index = 0; index < intArray.Length; index++) { sum += intArray[index]; } return sum; } public static void Main() { int[] arr = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; Console.WriteLine($"Sum of all the values in the array: { GetSumOfArray(arr) } "); } }
