Enter a string, the string in all lowercase characters such as char a [20]="bcadfgih
"
To smallest to the lowercase letters (a minimum z biggest) in the above, for example a [20] into "abcdfghi
"
(using a sorting algorithm)

To enter another one character such as char b='e', insert a finished sequence of [20], insert rule is inserted into the smaller than b and the characters of larger than b,

Such as the above a [20]="abcdefghi"

Sorting and insert operation, it is not difficult problem, it is suggested that the building Lord their first try, problems come up
