7.12. strings are mutable

You can change the letters in an string one at a time using the [] operator on the left side of an assignment.

The active code below changes the first letter in greeting to be 'J'.

This produces the output Jello, world!.

Put together the code below to creater a function <code>mixer<code> that takes in two strings and replaces every even index of the first string by the corresponding index of the second. It returns the modified first string. Example: <code>string_a = “food”<code> and <code>string_b = “summer”<code> . <code> mixer(string_a ,string_b )<code> makes <code>string_a<code> become “somd”.

Assume second string is greater than first.
