Compute the Sum of Even and Odd Numbers in a List

Certification: Basic Level Accuracy: 75% Submissions: 48 Points: 10

Write a Python program that computes the sum of even numbers and the sum of odd numbers in a given list separately.

Example 1
    

  • Input: numbers = [1, 2, 3, 4, 5, 6]
    • 

  • Output: Even sum: 12, Odd sum: 9
    • 

  • Explanation: 
      

    • Step 1: Initialize even_sum = 0 and odd_sum = 0.
      • 

    • Step 2: Iterate through each number in the list.
      • 

    • Step 3: For each number, check if it's even (divisible by 2) or odd.
      • 

    • Step 4: Even numbers: 2, 4, 6. Sum = 2 + 4 + 6 = 12.
      • 

    • Step 5: Odd numbers: 1, 3, 5. Sum = 1 + 3 + 5 = 9.
      • 

    • Step 6: Return both sums: Even sum: 12, Odd sum: 9.
      • 

    •
Example 2
    

  • Input: numbers = [8, 10, 12, 15, 17, 20]
    • 

  • Output: Even sum: 50, Odd sum: 32
    • 

  • Explanation: 
      

    • Step 1: Initialize even_sum = 0 and odd_sum = 0.
      • 

    • Step 2: Iterate through each number in the list.
      • 

    • Step 3: For each number, check if it's even (divisible by 2) or odd.
      • 

    • Step 4: Even numbers: 8, 10, 12, 20. Sum = 8 + 10 + 12 + 20 = 50.
      • 

    • Step 5: Odd numbers: 15, 17. Sum = 15 + 17 = 32.
      • 

    • Step 6: Return both sums: Even sum: 50, Odd sum: 32.
      •

Constraints
    

  • 1 ≤ list_length ≤ 10^6
    • 

  • -10^9 ≤ list[i] ≤ 10^9
    • 

  • Time Complexity: O(n) where n is the length of the list
    • 

  • Space Complexity: O(1)

  • Initialize two variables to store the sum of even and odd numbers
    • 
        
  • Use the modulo operator(%) to check each number's parity
    •

Steps to solve by this approach:

 Step 1: Initialize two variables to track the sum of even numbers and the sum of odd numbers.

 Step 2: Iterate through each number in the input list.

 Step 3: Check if the current number is even or odd using the modulo operator.

 Step 4: If the number is even (divisible by 2), add it to the even sum.

 Step 5: If the number is odd (not divisible by 2), add it to the odd sum.

 Step 6: Return a tuple containing both the even sum and odd sum.
