Given a string of both uppercase and lowercase alphabets, the task is to print the string with alternate occurrences of any character dropped(including space and consider upper and lowercase as same).
Input : It is a long day Dear. Output : It sa longdy ear. Print first I and then ignore next i. Similarly print first space then ignore next space. Input : Geeks for geeks Output : Geks fore

As we have to print characters in alternate manner, so start traversing the string and perform following two steps:-
- Increment the count of occurrence of current character in a hash table.
- Check if the count becomes odd, then print the current character, else not.
