Have a data file test2-2. In which there is a line of string, the string to a character array, and then a character array arranged a lower values for an even number of elements since the childhood, other elements, requirements, the entire string and output reordering subscript for an even number of elements,
Program test2-2 c, the realization of the function,
Data file test2-2. In the content of the see is as follows: a8V61tHZw # A
