Given a string, that contains special character together with alphabets (‘a’ to ‘z’ and ‘A’ to ‘Z’), reverse the string in a way that special characters are not affected. Examples: Input: str = "a,b$c" Output: str = "c,b$a" Note that $ and , are not moved anywhere. Only subsequence "abc" is reversed Input: str = "Ab,c,de!$" Output: str = "ed,c,bA!$"
