Sum the digits in an integer$)$: Write a method that computes the sum of the digits in

an integer. Use the following method header:

public static int sumDigits$($long n$)$

For example, sumDigits$(234)$ returns $9(=2+3+4).($Hint: Use the $\%$ operator to extract digits and the $/$ operator to remove the extracted digit. For instance, to extract $4$ from $234,$ use $234\%10(=4).$ To remove $4$ from $234,$ use $234/10(=23).$ Use a loop to repeatedly extract and remove the digit until all the digits are extracted. Write a test program that prompts the user to enter an integer then displays the sum of all its digits. Make a FLOWCHART diagram for the above program and explain the flowchart in detail.
