/*

|
Explanation :- a user gives a String (it can be incomplete uppercase or
|
|
|
|
|
|
partial uppercase) and then the program would convert it into a
|
|
|
|
|
|
complete(all characters in lower case) lower case string. The
|
|
|
|
|
|
logic we have used in the following program is: All the upper case
|
|
|
|
|
|
characters (A-Z) has ASCII value ranging from 65 to 90 and their
|
|
|
|
|
|
corresponding lower case characters (a-z) have ASCII values 32
|
|
|
|
|
|
greater than them. For example ‘A‘ has an ASCII value of 65
|
|
|
|
|
|
and ‘a‘ has an ASCII value of 97 (65+32). The same applies to other
|
|
|
|
|
|
characters.
