Develop a function to encrypt a string through a specific process. The function returns the encrypted string.
Write a Python function that encrypts a string by separating it into two halves. The first half includes letters from odd indices, and the second half includes letters from even indices. Merge these halves with the 'odd-indexed' half first. Repeat this process `n` times. The task assesses your basic skills in string manipulation, application of loops, and problem-solving. ### Parameters - `message` (str): A plain string that needs encryption. - `iterations` (int): The number of times the encryption process is repeated. ### Return Value - The function should return the re-arranged string after `iterations` number of times. ### Examples ```python # "0123456789" turns into "1357924680" after one iteration # Odd indexed characters (1,3,5,7,9) are moved to the front encrypt_string('0123456789', 1) # "1357924680" # "hello world" turns into "el olhlowrd" after one iteration # Odd indexed characters are moved to the front encrypt_string('hello world', 1) # "el olhlowrd" ```
