Finally, back in the "main()" method, it prints the result of the "sumDigits()" method, displaying the sum of the digits of the entered integer. Sample Output: Input an intger: 25 The sum of the digits is: 7 Flowchart: For more Practice: Solve these Related Problems: Find the sum...

The number of digits in the nth row is n. The sum of the numbers in the nth row is 2^(n-1). Each number is equal to the sum of the left and right numbers in the previous line. This property can be used to write the entire Yang Hui triangle. The first number in the nth row...

Give two non-empty linked lists to represent two non-negative integers. Among them, their respective digits are stored in reverse order, and each node of them can only store one digit. If we add these two numbers together, we will return a new linked list to represent their sum. ...
