Alex 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.

Solution
The problem is asking to create a program that calculates the absolute difference between the sum of digits at odd and even positions in a given number. The first digit is considered position 1.
Here is a step-by-step guide on how to solve this problem:
-
First, we need to get the input from the user. The input will be an integer number.
-
Next, we need to convert the integer into a string so that we can easily access each digit in the number.
-
We then initialize two variables,
odd_sumandeven_sum, to 0. These variables will hold the sum of the digits at odd and even positions respectively. -
We then iterate over the string representation of the number. For each digit, we check if its position is odd or even. If the position is odd, we add the digit to
odd_sum. If the position is even, we add the digit toeven_sum. -
After iterating over all the digits, we calculate the absolute difference between
odd_sumandeven_sumusing the formulaabs(odd_sum - even_sum). -
Finally, we print the result.
Here is a Python code snippet that implements the above steps:
def calculate_difference(n):
n = str(n)
odd_sum = 0
even_sum = 0
for i in range(len(n)):
if (i+1) % 2 == 0:
even_sum += int(n[i])
else:
odd_sum += int(n[i])
return abs(odd_sum - even_sum)
print(calculate_difference(5674)) # Output: 2
print(calculate_difference(1234567)) # Output: 4
print(calculate_difference(10)) # Output: 1
print(calculate_difference(10000000)) # Output: 1
This code works for any integer n such that 10 ≤ n ≤ 107.

Given a positive integer 'x' (with even number of digits in it), write an algorithm and the subsequent code to compute the difference between the sum of the digits occuring in the alternate positions (starting from the first position) and the sum of the digits occuring in the alternate positions,starting from the last rightmost position of 'x'For example, consider the number 8975. The sum of the digits that occur in the alternate positions from the first position is 8+7=15. The sum of the digits that occur in the alternate positions, starting from the rightmost position is 5+9 = 14. Difference between the two sums is 1 (=15-14). Similarly, for the number 5798, the difference between two sums, is 1. Note: Read the input as a number and do entire processing as a numberC++ compilers can compile C code alsoInput format First line contains the positive integerOutput format :First line should contain the difference between the sum of the digits occuring in the alternate positions (starting from the first position) and the sum of the digits occuring in the alternate positions (startting from the last rightmost position).
