Write a Python simple program, to ask the user input a string, and display only the first quarter (one fourth) and the last quarter substrings of the input string. The program should be written in ""A2Q1A.py". Requirements: 1. Ask user a string, and assign it to a variable astr 2. Extract the first quarter substring of the input string to a variable fStr, with slicing technique 3. Extract the last quarter substring of the input string to a variable estr, with slicing technique 4. Join two extracted substrings above, and display the result as sample output below 5. Assume the number of characters in the string is divisible by 4. Sample program output: Enter a string: 12345678 Joined string is 1278
