SDET Java Program 05: Reverse a string without affecting special characters or Spaces

Simple Solution:
1) Create a temporary character array say temp[].
2) Copy alphabetic characters from the given array to chararr[].
3) Reverse chararr[] using standard string reversal algorithm.
4) Now traverse input string and temp in a single loop. Wherever there is an alphabetic character is input string, replace it with the current character of chararr[].
Efficient Solution:
Time complexity of the above solution is O(n), but it requires extra space, and it does two traversals of an input string.

The example contains:-
Q1.
Input- "abc! ssaaDs, asda%"
Output- "ads! asDaas, scba%"
