Problem Link - Sum of Array elements in Arrays
Problem Statement:
Calculate the sum of all the array elements
Approach:
- Initialize a variable with 0 to store the sum (let’s call it
sum). - Iterate through the array and add each element to
sum. - The variable
sumwill contain the sum of all elements after the loop finishes.
Complexity:
- Time Complexity:
O(N)Nis the size of array. We are traversing through the whole array. - Space Complexity:
O(1)No extra space used.
