Single File Programming QuestionProblem StatementAlex is creating a utility to evaluate a user's numerical input. The program calculates the absolute difference between the sum of digits at odd and even positions, where the first digit is considered position 1. Users enter a sequence of digits, and the program outputs the result.ExampleInput:5674Output:2Explanation:The sum of the even-position digits 6 and 4 is 10. In the odd position, the sum of digits 5 and 7 is 12. So, the absolute difference is |10-12| = 2.Input format :The input consists of an integer n.Output format :The output prints the difference between the sum of the odd and even position digits in the given integer.Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases will fall under the following constraints:10 ≤ n ≤ 107Sample test cases :Input 1 :5674Output 1 :2Input 2 :1234567Output 2 :4Input 3 :10Output 3 :1Input 4 :10000000Output 4 :1

Solution
To solve this problem, you can follow these steps:
- Convert the integer to a string to easily access each digit.
- Initialize two variables,
odd_sumandeven_sum, to 0. These will hold the sum of the digits at odd and even positions, respectively. - Iterate over the string. For each character, convert it back to an integer. If the index of the character is odd, add the digit to
odd_sum. If the index is even, add the digit toeven_sum. - After the loop, return the absolute difference between
odd_sumandeven_sum.
Here is a Python solution following these steps:
def calculate_difference(n):
n = str(n)
odd_sum = 0
even_sum = 0
for i in range(len(n)):
if i % 2 == 0:
odd_sum += int(n[i])
else:
even_sum += int(n[i])
return abs(odd_sum - even_sum)
This function works by converting the integer to a string, then iterating over the string. For each character, it checks if the index is odd or even, and adds the digit to the appropriate sum. Finally, it returns the absolute difference between the two sums.
