Summary
This problem involves calculating the sum of n numbers. The key concept involved is basic arithmetic operations and loops.
Detailed Explanation
The problem requires you to find the sum of a given set of numbers. A common approach to solve this problem would be to use a loop to iterate over each number, add it to a running total, and return the result.
Here's a step-by-step breakdown of the solution:
- Initialize a variable
sumto zero. - Iterate over each number in the given set using a for loop or while loop.
- Add each number to the
sum. - Return the final value of
sum.
Time complexity: O(n), where n is the number of elements in the input array.
Space complexity: O(1), as we only use a constant amount of space to store the sum and loop variables.
Optimized Solutions
Java
public class SumOfNNumbers {
public static int findSum(int[] numbers) {
int sum = 0;
for (int number : numbers) {
sum += number;
}
return sum;
