Answer:

See Explanation Below

Explanation:

Follow the steps below.

1. Start Session

2. Assign the session you want to preserve ( $_SESSION['variablex'] ) to a variable

3. Destroy all session (including the one you want, $_SESSION['variablex'])

4. Reassign the contents of the variable you created in (1) above to $_SESSION['variablex'].

The code is as follows (comments explain each line)

<?php

session_start(); // Start session

$variable = $_SESSION['variablex'] ; // assign $_SESSION['variablex'] to $variable

session_destroy(); // Destroy sessions

$_SESSION['variablex'] = $variable; // assign $variable back to $_SESSION['variablex'] to

// You can continue your code (if you have any), here

// End of solution

?>

Aneli [31]

Answer:

 The solution code is written in Python 3

  1. digits = input("Enter 9 digits: ")
  2. multiplier = 1
  3. total = 0
  4. for x in digits:
  5.    total += int(x) * multiplier  
  6.    multiplier += 1
  7. checksum = total % 11  
  8. if(checksum == 10):
  9.    print(digits + "X")
  10. else:
  11.    print(digits + str(checksum))

Explanation:

Firstly, use input function to get user input for 9 digits (Line 1)

Next we can use a for-loop to estimate the summation (d1 * 1 + d2 * 2 + d3 * 3 + d4 * 4 + d5 * 5+ d6 * 6 + d7 * 7 + d8 * 8 + d9 * 9) ( Line 6-8)

Then only apply % operator to get the remainder of total and get the checksum (Line 10)

Next create if and else statement to print the digits string joined with X if checksum is 10 else join digits string with checksum value (Line 12 -15)
