2535. Difference Between Element Sum and Digit Sum of an Array

Easy

Array Math

Problem Explanation

Explanation:

To solve this problem, we need to calculate the element sum and digit sum of the given array.
We can iterate through the array to calculate the element sum.
To calculate the digit sum, we iterate through each number in the array, convert it to a string, and then sum up all the digits in each number.
Finally, we return the absolute difference between the element sum and digit sum.

Time Complexity: O(n) where n is the number of elements in the array. Space Complexity: O(1) since we are using a constant amount of extra space.

Solution Code

class Solution {
    public int subtractProductAndSum(int n) {
        int elementSum = 0, digitSum = 0;
        for (int num : nums) {
            elementSum += num;
            String numStr = String.valueOf(num);
            for (int i = 0; i < numStr.length(); i++) {
                digitSum += numStr.charAt(i) - '0';
            }
        }
        return Math.abs(elementSum - digitSum);
    }
}
