(7) Accept a 4-digit number from a user. Your task is to create a simple encrypted corresponding value
of this number. First separate each number into its individual digits. For each individual digit, if the
individual digit is greater than or equal to 5, subtract that value from 9. Output the new value (in its
individual digits) which would now represent the encrypted corresponding value. For example, if the
user entered 5678, the encrypted corresponding value would be 4 2 3 1. (Required: IPO chart,
Pseudocode, C-program and Python)
